What is the difference between a 2001 Mercedes-Benz SL500 and SL500R and how do you tell the difference?
How do you tell the difference between the 2001 Mercedes Benz SL500 and SL500R. We were looking at a Mercedes Benz SL500 and was told that it paced the Formula One Race and was only 1 of 20 made. How can you tell for sure that this was the case.
Thanks.
