If you've been sleeping on BIDR Auctions, wake up — because May 2026 is shaping up to be one of the most spectacular months in the platform's history. New auctions are dropping every single day, spanning everything from analog Italian motorcycles and golden-era American muscle to track-ready Porsche rarities that most collectors will never see in person, let alone have a chance to bid on. Whether you're a diehard JDM fanatic, a Shelby devotee, or someone who just wants to own something extraordinary, there is something in this lineup with your name on it.

Let's break down every car currently live and launching through the end of May — with the details that actually matter.

LIVE NOW — Bidding Open, Clock Ticking

1999 Nissan Skyline GT-R V-Spec (R34) — BIDDING LIVE - Closes: May 21, 2026 

If you've been waiting for your shot at the holy grail of Japanese performance cars, this is it — and it's happening right now.

The R34 Nissan Skyline GT-R V-Spec is not a car that needs an introduction to anyone who has ever cared about going fast. It is, simply put, the benchmark against which every other Japanese sports car of its era is measured. The RB26DETT twin-turbocharged inline-six — officially rated at a gentlemanly 276 horsepower, actually producing considerably more — is one of the most tunable, durable, and characterful engines ever bolted into a production car. Pair it with the legendary ATTESA E-TS Pro all-wheel-drive system and an active rear LSD, and you have a machine that still embarrasses far more expensive modern hardware on a twisty road.

This particular V-Spec presents in Sonic Silver with just 34,255 total kilometers (28,363 km since a documented odometer replacement at 5,892 km). It was legally imported into Washington State in December 2025 with a clean title — no grey-area games here. Tasteful upgrades include a Nismo muffler, Mines midpipes, and an Impul ECU with a steering wheel-mounted boost controller. The BBS wheels look period-correct. The multifunction display — the one that shows boost, temps, and throttle angle in real time — still works. Of course it does.

R34 GT-Rs are now federally importable into the U.S., and the market has responded exactly as everyone predicted. Clean, documented examples like this don't come around often. This is the one you tell your kids about.

Current Bid: $15,000 | [Bid Now at bidrauctions.com](https://www.bidrauctions.com/auctions/1999-nissan-skyline-gt-r-v-spec-01)

📅 LAUNCHING THIS WEEK

2005 Ducati Monster S2R 800 — Opens May 18 - Closes: May 25, 2026

Before the electronics revolution turned motorcycles into rolling video games, Ducati made bikes that communicated through mechanical sensation alone. The Monster S2R 800 is the finest expression of that philosophy — a machine that looks like a sculpture, sounds like a thunderstorm, and rides like it was tuned by someone who actually cares about your wrists.

At its heart is the 803cc air-cooled "Desmodue" 90° L-twin — a mechanically simple, sonically extraordinary engine with a torque curve that rewards patience and punishes impatience in the best possible way. The S2R borrowed its single-sided swingarm and visual aggression from the big-bore S4R, giving it an elevated presence that smaller Monsters simply don't have. Marzocchi inverted forks, a Sachs monoshock, and classic Ducati red trellis frame construction make this a rolling piece of art that also happens to be legitimately quick.

In a world drowning in ride-by-wire, cornering ABS, and six-axis IMUs, the S2R 800 is a magnificent anomaly: a motorcycle that talks to you directly, no interpreter required. Modern classic prices have been climbing steadily, and the window to own one of these without paying collector premiums is closing. Don't sleep on it.

1965 Ford Mustang Fastback — Early Production San Jose Build — Opens May 19 - Closes: May 26, 2026

There are 1965 Mustang Fastbacks, and then there is this 1965 Mustang Fastback.

VIN 5R09F178789 is a decoder ring into one of the most historically fascinating windows in Mustang production history. That second digit — "R" — places this car's birth at the San Jose, California assembly plant, one of only three factories building the Mustang during the pony car's explosive launch years. The fifth digit — "F" — identifies the 260 cubic inch V8 as the original factory engine, a unit that was being phased out in favor of the 289 by the time this car rolled off the line. A Fastback wearing an F-code 260? That means this car was built right at the opening bell of the Fastback body style's production run, in the late summer and fall of 1964 — what collectors have always called a "1964½."

The car today wears its rebuilt 289ci V8 with Mickey Thompson valve covers and an Edelbrock four-barrel on top, breathes through headers, and sends power through a freshly rebuilt four-speed manual with a B&M T-handle shifter. The recent repaint in Raven Black is deep and uniform. Front disc brakes, GT-style dual exhaust, 15-inch Magnum 500-style wheels, and traction bars round out an honest, period-correct build that drives as good as it looks.

For the collector who wants real provenance in their Fastback — not just a nice car, but a significant one — this VIN combination is genuinely rare.

1968 Superformance GT40 MKI — Opens May 20 - Closes: May 27, 2026

The Ford GT40 beat Ferrari at Le Mans four consecutive times. It became the subject of a major motion picture. It remains, to this day, one of the most beautiful and consequential race cars ever built. And this — chassis GT40P2451, dressed in magnificent Guardsmen Blue — is your chance to own a piece of that legacy.

Superformance GT40s are not replicas. They are continuation cars, built under official license from Safir GT40 Spares Ltd., the exclusive legal holder of the GT40 trademark and registry. Every chassis carries an authentic GT40P number and is eligible for the official GT40 registry. This car is the real deal in every way that matters.

Beneath that achingly beautiful low-slung body lives a fuel-injected PrestigeMotorsports 427ci V8 mated to a Quaife five-speed manual transaxle — the mechanical heart of a proper race car, made street-friendly with modern reliability. At just 3,519 miles, it has barely been kissed. The period-correct bucket seats, the riveted body, the scoop-low cockpit — it all conspires to make you feel like you're lining up on the Mulsanne Straight in 1966.

Own a Le Mans legend. For real.

2020 Ducati Panigale V4S — Opens May 21 - Closes: May 28, 2026

In 2018, Ducati did something its fans thought might never happen: they replaced the L-twin engine in the Panigale with a V4. Not just any V4 — the Desmosedici Stradale, a counter-rotating, 90-degree V4 derived directly from Ducati's MotoGP program. The result was 214 horsepower in an accessible, manageable package that immediately reset the standard for what a production superbike could be.

This 2020 Panigale V4 (standard specification) delivers the full Desmosedici experience with the aluminum "Front Frame" architecture, fully adjustable Showa/Sachs suspension, and a six-axis IMU governing an electronics suite that includes lean-sensitive traction control, slide control, wheelie control, engine brake control, and cornering ABS. The bi-directional quickshifter means you never have to pull the clutch under load. The four ride modes mean you can actually use all 214 horsepower rather than just fear it.

In Ducati Red, with the functional aerodynamic winglets and that screaming V4 note — this is what a modern superbike looks and sounds like at its absolute best. The window to own a 2020 at a pre-appreciating price will not stay open forever.

2023 Audi R8 V10 Performance — Opens May 22 Closes: May 29, 2026

The 2023 Audi R8 is not just a supercar — it's a farewell letter to everything the internal combustion supercar era stood for. The naturally aspirated 5.2-liter V10 it shares with Lamborghini is one of the last of its kind: a high-revving, naturally breathing ten-cylinder that climbs to its redline like a musical crescendo. As electrification advances and regulations tighten, the days of buying a new V10 supercar with a manual soul are over. The R8 was one of the last. This 2023 example is among the very final production runs.

This particular car goes further: it's been fitted with a VF Engineering supercharger system for substantially elevated output beyond the already ferocious stock specification, and the entire exterior is wrapped in full paint protection film to preserve the finish underneath. The Quattro all-wheel-drive system keeps it planted through all that power, while Audi's Magnetic Ride suspension and the Virtual Cockpit instrument cluster make it as livable as a daily driver when you're not extracting its full potential.

Final-generation naturally aspirated V10 supercars with supercharger upgrades don't arrive on the market every week. Collector attention is already focusing on cars like this. The question is whether you'll be watching from the sidelines or holding the keys.

 📅 LAST WEEK OF MAY — The Grand Finale

2021 Rezvani Hercules 6x6 — Opens May 25 Closes: June 1, 2026

Most trucks carry things. The Rezvani Hercules 6x6 carries a statement — specifically, the statement that you have decided conventional vehicles no longer apply to you.

Rezvani Motors stretches a full-size American truck frame, adds a third axle, re-engineers the drivetrain to power all six wheels (configurable between 6x2, 6x4, and full 6x6 on demand), and wraps the whole thing in bespoke custom bodywork that makes a stock Ram or F-250 look like office furniture. The result is one of the most genuinely extreme production vehicles ever offered for public sale.

This 2021 example is powered by the 6.4-liter SRT V8 Hemi — 500 horsepower, 8-speed automatic — backed by Fox Performance Elite adjustable shocks, a Dana 60 axle setup with air lockers, 37-inch tires on 24-inch TIS wheels, and a roof-mounted light bar you can see from the next county. The custom interior wears black leather with blue contrast stitching, Alcantara headliner, Hercules-embossed headrests, ambient lighting, upgraded infotainment, and a subwoofer system mounted under the rear bench. One owner. Clean CARFAX. Just 12,624 miles.

There are expensive trucks. There are attention-commanding trucks. And then there is this — something genuinely in a category of its own.

2022 BMW Alpina XB7 — Opens May 26 - Closes: June 2, 2026

BMW builds the X7. Alpina perfects it.

The Alpina XB7 is what happens when an independent engineering house with decades of motorsport DNA and obsessive attention to detail takes BMW's flagship three-row SUV and quietly transforms it into something more refined, more powerful, and more driver-engaging than any badge on its nose would suggest. Alpina's reworked 4.4-liter twin-turbo V8 delivers a broad, effortless powerband that moves this large SUV with the kind of urgency usually reserved for much smaller vehicles, while Alpina's bespoke suspension tuning strikes a balance between body control and ride quality that the standard X7 simply cannot match.

The XB7 doesn't shout about itself — it doesn't wear a garish body kit or aggressive afterthought aero. It differentiates itself through signature Alpina wheels, subtle badging, and a sense of calibration that reveals itself in the driving. Inside, flagship BMW craftsmanship is elevated further by Alpina-specific materials and finishes. Genuine three-row SUV practicality. A GT touring experience that grand tourers twice its price struggle to match.

For the buyer who needs the space but refuses to sacrifice the experience — the Alpina XB7 is the answer.

2020 Porsche 911 Carrera S (992) — Opens May 27 - Closes: June 3, 2026

Every generation of the Porsche 911 is supposed to be the best one yet. The 992 actually delivers on that promise.

The 992-generation Carrera S arrived in 2020 with a fundamentally redesigned chassis, wider tracks front and rear, an 11% more direct steering ratio, and a twin-turbocharged 3.0-liter flat-six producing 443 horsepower through an 8-speed PDK dual-clutch to the rear wheels. Zero to 60 in 3.5 seconds. 3.2 with launch control. 191 mph flat out. From a car that can sit comfortably in city traffic and cruise a continent in total silence — which is precisely why the 911 has been the benchmark sports car for over sixty years.

This particular example takes "well-specified" to a new level. The options list carries $52,000 in factory content on top of an already substantial base price: the full Aerokit with active rear wing, carbon fiber roof (for weight reduction *and* that stunning two-tone appearance), carbon fiber exterior mirrors, RS Design 20/21-inch staggered wheels, Sport Design side skirts, and deviated clear taillights. The chassis package includes PASM adaptive dampers, PDCC active anti-roll bars, rear axle steering (the single option that most transforms the 992 driving experience), Sport Chrono with launch control, and front axle lift. Full PPF from new. Just 4,851 original miles. Clean CARFAX. Recently serviced.

This is not a 911 that someone bought and thrashed. This is a 911 that someone built at the top of the configurator and barely drove. Don't miss it.

1970 Chevrolet Chevelle SS 396 — Opens May 28 - Closes: June 4, 2026

1970 was the high-water mark of the American muscle car era, and no car from that year captures the moment better than the Chevelle SS. The shape is perfect — wide shoulders, long hood, purposeful stance — and in 1970 it came with big-block power that could embarrass virtually anything else on the road. The SS396 is the purist's choice: the engine Chevrolet originally designed specifically for the Chevelle, delivering 350 horsepower of accessible, thunderous torque that makes every drive an occasion.

This example wears Fathom Blue with twin white stripes — one of the most striking color combinations available on the 1970 Chevelle — and the pairing of the big-block with a 4-speed Muncie manual and a 12-bolt rear end is exactly what collectors seek. Power steering and front disc brakes make it drivable in the real world. The cowl induction hood reinforces its performance intent. At just 30,599 miles, described as a garage-kept Florida car with no rust, it presents as a beautifully preserved example from one of the most celebrated model years in American automotive history.

Current bid sits at $65,000. This is the real deal.

1965 Shelby Cobra 427 Challenge Car (CSX4257) — Opens May 29 - Closes: June 5, 2026

This is not simply a Shelby Cobra. This is CSX4257 — a factory-built Shelby Cobra 427 Challenge Car, assembled in 2001 as part of the limited-production **Shelby Cobra Challenge Senior Racing Series, a one-make program that was designed to put notable drivers into identically prepared Cobras for the 2002 season. The series never launched. The cars were built anyway. And this one has just 99 miles on it.

Under the skin lives a Ford FR9 Stock Car 351ci V8 built by Roush Yates Engines — one of the most celebrated racing engine builders in American motorsport history — paired with a five-speed manual, an MSD Soft Touch rev-control unit, and an ATL Racing fuel cell. The cockpit is equipped with Simpson four-point harnesses, AutoMeter Pro-Comp gauges including a 10,000-rpm tachometer, a tubular roll bar, battery cutoff switch, and fire extinguisher. The 15-inch Halibrand-style aluminum wheels wear Goodyear Blue Streak Sports Car Special race tires. The Shelby American placard on the dash reads CSX 4257.

This car is sold on a Manufacturer Statement of Origin and intended for track use. It is a direct, documented piece of Shelby American history. In 99 miles, it has never had the chance to become anything less.

2022 Porsche 911 GT2 RS Clubsport 25 "Manthey Racing" (05/30) — Opens May 31 - Closes: June 7, 2026

Save the best for last.

There are rare cars. There are historically significant cars. And then, sitting in an entirely separate category from everything else, is the 911 GT2 RS Clubsport 25 "Manthey Racing" — of which **exactly 30 were built on earth**, and this is number 05/30.

To understand what this car is, you have to understand what Manthey-Racing means. Olaf Manthey — 1990 Porsche Carrera Cup champion — founded his operation near the Nürburgring in 1996, and for the next quarter century, his team *owned* the most demanding stretch of tarmac in the world: seven 24-hour victories, and in 2021, a shattering 6:38.835 production car lap record in the GT2 RS MR. Porsche bought a 51% stake in 2013. To celebrate 25 years of this partnership, they built 30 cars. This is what it means to have thirty of something.

The car starts with the GT2 RS Clubsport's 700-horsepower 3.8-liter twin-turbo flat-six driving the rear wheels through a seven-speed PDK. Manthey then rebuilt the world around it. The entire body architecture was rethought, adopting the central radiator concept from the 911 GT3 R — the "Grello" endurance racer. The new carbon fiber hood wears twin extraction vents. The front bumper carries Grello-inspired aero flicks. Deep aerodynamic door sills nod to the original 935 of 1976. The swan-neck rear wing supports uninterrupted lower-surface airflow. The livery — green and yellow, every splash of color earning its place on a functional surface — was designed by **Grant Larson**, the Style Porsche designer behind the 911 RSR, the GT3 R, and the 935 itself.

Underneath: suspension from the 2019 935, 18-inch center-lock BBS wheels, four-stripe DRL racing headlights traced to the Le Mans-winning 911 RSR.

This example, chassis shows just **441 delivery and testing kilometers** and has never turned a competitive lap. It has been offered in as-delivered condition since the day it left the factory. Full Porsche Motorsport delivery documentation is included.

There are only two words left to say: bid accordingly.
