I've had Toyota's, Acura's, BMW's, Ford's, and finally this Nissan. It is hands down the best car I've ever owned. It is rewarding to drive, roomy, comfortable, frugal, and VERY reliable. I've had absolutely no problems, and there is hardly any preventative maintence (unlike Honda's and Toyota's). I've owned Integras and Tercels and this Nissan is actually much cheaper to own and operate then both of those.

Maybe rear wheel drive, but for most drivers this is no big deal.
