bmw 645i?
mate has one, really nice cars, and pretty rapid too!
few of my mates just done a few thousan miles in one (euro road trip to stelvio pass, nurburgring etc etc etc. with a few cars rangeing from porsch & ferraris to vx220t) and they enjoyed it, said it was comfy for the thousands of miles, and fast enough to keep. (one of the guys has a 300+bhp 500ft/lbs A4 and he was aparently like a child in a sweet shop when he had a drive)
