If you've been considering dropping $452,750 on a new Mercedes SLR McLaren but were worried the thousand or so other SLR's in existence may detract from your own supercar's exclusivity, eBay has another option that may be exactly what you're looking for.

Originally created for a United Arab Emirates citizen who desired to own the fastest, individually owned car in the world (or so the rumors say), the vehicle pictured is the product of a joint development between Mercedes and Lotec. Highlights include a light-weight carbon fiber body, 1000 horsepower 5.6 Liter V8 with Garrett twin turbo chargers, a Hewkand 5-speed racing transmission and 4 Ram AP IMSA racing brakes.  The result is a Mercedes supercar capable of accelerating from 0-60 mph in 3.2 seconds, 0-125 mph in 8.08 seconds, and reaching a top speed of 268 mph.  As for exclusivity, it's the only one in existence.

If you're interested, bidding starts at a mere $350,000, with the reserve not met.

For more info, you can view a number of photos below, or head over to eBay for the full auction listing.
