BMW M1 art car by Frank Stella headed for the auction block

The original Bavarian supercar was painted by the celebrated artist Frank Stella in 1979. But while BMW has commissioned many art cars (including another M1 by Andy Warhol and a 3.0 CSL also by Stella) since the program kicked off in 1975, this is the only one that was officially sanctioned by the factory for a private client, whereas all the others remained in the German automaker's private collection. This, then, represents an extremely rare opportunity to acquire an original BMW art car.

The vehicle has been part of the museum's collection since 1999, and will be auctioned by Bonhams this coming August at the Quail Lodge in Carmel, California, where it's expected to fetch around half a million dollars, an estimate we can see it blowing right past. Us? We're just hoping that BMW itself decides to bid on the car so that this Stella M1 can rejoin its celebrated relatives in the German automaker's collection.

If you're in New York and want to catch a glimpse at this one-of-a-kind rolling work of art, it's currently on display outside Bonhams' offices in the atrium of the IBM Building at 56th and Madison.
