i know most you guys don't like the yank stuff, but for a hell of a lot less money you can have something that goes round the Nurburgring quicker (unless i saw the last M5's time), and i think looks much better, is more tunnable, 6.2 v8 supercharged, 580hp from the factory, 20" wheels, £35,000, did the nurburgring 7:41.27,

ok, down side, the driving seat on the wrong side, but i think for looks alone, it would get my money, and in 5 years time it would probably be worth more than the M5
