I love my Euro M6, despite its faults, which are manifold. They're a bit heavy and lack the tossable feel of an E9, but in modern traffic they're safer, quieter, and have more creature comforts. I would happily spend good money on a very well maintained Euro M6 before I'd buy a new car. I'd have something unique, stylish, usable and a future collectible, for half the price of a new car. In fact, Bimmer just called the M635CSI one of the cars that will soon be "collectible", along with non-CSL E9s, M Coupes, and several others. I had the pleasure of driving a 79K mile time capsule Euro M6 last weekend and it was amazing. Sadly mine's been violated a thousand ways from Sunday and sometimes I'm not sure that even I have the stomach to nurse her back to the condition she deserves. I didn't pay a lot for it, but it needs at least $5K put in to it to become respectable and reliable. But sound and power delivery from that M88 engine and the way she handles and gobbles up freeway miles are so seductive.
