It's the end of the run for the McLaren SLR Roadster, but Mercedes wants to give Yanks another shot at owning one. Beginning November 1, those of you who still have bank accounts can sign up for the auction of the final topless SLR to be sold in the U.S.

You'd be right to assume the final edition of a limited run model would bring a huge premium when it goes on the block, as collectors have always put higher values on the first and last of most anything. But if you plan to take this particular knick-knack home, prepare to drain both savings accounts. Mercedes says the car will be the only SLR Roadster wearing Sienna Pearl metallic paint and Tobacco Brown leather. So when you show up to accept your Oscar, no one else will be driving the same one.

The auction begins November 20 at 1 p.m. EST and ends that night at 5 p.m. Bidding starts at $529,500, and anything above that will go to St Jude Children's Research Hospital. Thanks for the tip, James!
