Q45's and M35/45's are totally different cars. not to mention the Q is a bit outdated even w/ the newer generation. the other cars mentioned in this thread, specifically the lexus, are too tame. all that electronically controlled traction crap is like a babysitter who gets pissed for catching you watching jackass on mtv and makes you sit and eat cauliflower for dinner. the M allows a lot more room for fun driving, like a chaperone who'll keep an eye on you but will let you have your 'fun' (let your imagination go on that one) as long as you dont go and jump in the center of a major intersection.
