Acura Auctions Avengers NSX Roadster for Charity
Acura has opened a no-reserve auction for the one-off NSX Roadster created for Marvel’s 2012 film The Avengers, giving a collector the chance to buy the screen-used “STARK 33” car driven by Tony Stark. The online Cars & Bids auction is scheduled to close Saturday, October 31, at 2 p.m. PDT.
This is not a conventional first-generation NSX, and it is not a road-legal preview of a production model. Acura and the auction listing describe it as a functional movie prop and manufacturer concept prototype that cannot be titled, registered or operated on public roads.

A 1991 NSX beneath the superhero body
Acura’s Advanced Design Studio in Los Angeles designed the Roadster specifically for the film. Trans FX in Oxnard, California, constructed its hand-built resin-and-fiberglass body over a 1991 Acura NSX donor car.
The shape was intended to preview the second-generation NSX concept shown in 2012, rather than reproduce the original car’s production bodywork. Its Hot Rod Red paint was matched to Iron Man’s armor, and the vehicle retains the screen-used “STARK 33” plate.
Underneath the custom body is the first-generation NSX’s 3.0-liter, 24-valve VTEC V6. The Cars & Bids listing rates it at approximately 270 horsepower and 210 pound-feet of torque, sent to the rear wheels through a five-speed manual transmission. The car also has aftermarket sport seats, 18-inch front wheels and 20-inch rear wheels.
Those mechanical specifications come from Acura and the seller’s auction listing; Chiefs Review has not inspected or driven the vehicle. Its value rests as much on its film history and one-off design as on the NSX hardware underneath.
The buyer gets a prop, not a street car
The winning bidder will receive the car on a bill of sale, along with a certificate of authenticity, one key, two fobs and a signed photo of an Acura creative director with the NSX. The transaction is also subject to a usage agreement.
Acura’s listing states plainly that the Roadster cannot be registered, titled or driven on public roads. It is sold as-is without a warranty. Disclosed condition issues include fragile custom bodywork, paint cracks around the C-pillars, micro-scratches on several exterior panels, scuffed interior trim and a warped driver-side armrest.
That makes the car better suited to a collection, museum or static-event program than normal ownership. A bidder should not assume that its Honda VIN, running engine or manual transmission creates a path to road registration.
Auction proceeds go to charity
Cars & Bids says 100% of the winning-bid proceeds will be donated to a charity selected jointly by the buyer and seller. American Honda also plans to reimburse the winning bidder’s standard buyer fee after the sale.
Acura separately says it will guarantee a contribution to the Sundance Institute, which supports independent artists and emerging voices. The company did not state a guaranteed sale price or a reserve because the auction is listed at no reserve.
The NSX Roadster is scheduled to appear at the Las Vegas Concours on October 31, alongside the Acura NEXERA Vision, before bidding closes at 2 p.m. PDT. Because bids can change rapidly, prospective buyers should use the live listing rather than any earlier reported price.
Why this NSX matters
The car captures an unusual moment when Acura used Hollywood to bridge two NSX generations. Its 1991 chassis represents the original aluminum-bodied supercar, while the costume body anticipated design ideas associated with the second-generation model.
It also fits Acura’s current habit of using one-off builds to connect performance cars with wider culture. Chiefs Review recently covered the ADX CZ-77 concept inspired by BMX rider Coco Zurita and Vans. The Avengers Roadster predates that project by more than a decade, but the creative formula is familiar.
For collectors, the appeal is straightforward: this is a functioning, factory-designed film prop with documented screen history and recognizable NSX mechanicals. The limitation is equally important—the winner is purchasing a piece of automotive and movie culture, not a street-legal supercar.
