I'm pretty sure the MS3 pulls harder than the Max. Especially from a roll and up to highway speeds, and especailly x2 with some mods. The Maxima has a pretty decent powerplant, but is HEAVY compared to the MS3.
but... I'd still like to know how it feels to drive. A big, cushy, slushbox sedan that can edge out a good amount of cars on the road has to be a bit of a laugh. Also, is there really an aftermarket support for those things (the new gen) beyond the usual VIP style and other visual accesories? Have fun with the ride man.
