I've got a friend with a 635csi. He has new bilstein shocks and lowering springs and michelin pilots on 8 inch wide wheels and the thing still handles like a tank. They are great cars for driving around town and on the highway but I couldn't see myself wanting one. The m6 is alot more expensive as far as the motor goes but other than that most of the parts are the same as the regualar 6 as far as I know.
