Iron Man’s one-off NSX was based on a 1991 V6 with 252k on the clock

Here’s a potentially fun fact. The one-off Acura NSX Roadster driven by Robert Downey Jr as the fictional tech billionaire Tony Stark in 2012’s The Avengers was based on a Mk1 NSX bearing 252,000 miles on its clock.

Two hundred and fifty two thousand miles! That’s what you’d politely call ‘high’, or if you’re the proud owner of a Toyota Hilux, ‘barely run in’.

While TopGear.com confirms the meaning of 'fun fact', Acura itself said it was a “well-used” 1991 car that provided the bones onto which a hand-crafted resin and fibreglass body was mounted. It also benefitted from a two-inch suspension drop, 18s and some dandy new seats before its starring role in the lightly massive superhero movie.

These informations have arrived because Acura has rolled out its literal movie star for this year's Monterey Car Week, where it’ll make its first public appearance in 13 years. And the old timer hasn’t aged a day.

And if you want to own a resin and fibreglass one-off Acura with a very ‘well-used’ V6 underneath - Tony Stark's actual car! - Acura will begin accepting what it’s calling ‘hand raisers’ this week ahead of putting it up for auction next year. Yes, we agree it could have used a different term.

“We knew it would have to be a reliable vehicle for filming, not just a static display, and we couldn’t come up with anything that would be more reliable than an original Acura NSX,” said… Acura exec advisor Dave Marek. He was the creative director that led the team to design this one-off.

So, fancy taking on the role of Tony Stark? At least the number plate’s all ready for you…
