You could have a look at a Mercedes-Benz SL (R107) although these are expensive now. Maybe a P38 Range Rover or a Bentley Arnage Red Label. If you'd like to go a bit more modern, then perhaps one of the first Audi TTs with the DSG box like the 2003 3.2 is an option (although the boxes are fragile) or something like a Smart Roadster. Also worth a look might be an American muscle car like a Mustang, or you could go for a high-performance model like a BMW M3 or Mercedes-Benz AMG. Feeling flush? Then how about a Nissan GT-R.
