if you want the fastest thats new & stock, the new kia/hyundai twins are pretty damn quick, & supposivly very nice
but the new 2008s Chrysler offerings are rumored to have gone up in quality due to new quality controls from Diamler, so i guess the new 5th gens won't suck like the 3rd & 4th gens did
& the Toyotas & Honduhs are pretty nuice too, & pretty easy to work on, body wise
but i guess iots your preferance, do alot of test drives & narrow down what you think is best for you
