2007 Nissan Maxima 3.5 SL 4dr Sedan (3.5L 6cyl CVT)
Superior acceleration, ride. Real highway cruiser in the best sense of the term. Drivetrain is a pleasure (world class VQ + new CVT = even better). The breaking in process gives me an excuse to modify acceleration, but I think I'll be doing it just for fun for a long time (swoops up nicely from 50-80+ without effort). The CVT, in my humble opinion, gives this car a performance advantage, as well as a nice aesthetic. Speaking of aesthetics, this Nissan provides what is too lacking in most competitors: an actually good looking car that you can connect to on an emotional level, in addition to being a fine machine. The 07 interior much better than 06.
Engine performance, CVT (more of a performance enhancement than a "nanny"), the new interior, intelligent key. Fun factor ++
Navigation could be simpler (but I'm still in the learning curve). Otherwise not much: this is clearly a very well thought out and designed car.
