2004 Nissan Altima 2.5 SL 4dr Sedan (2.5L 4cyl 4A)
I bought the Altima new and have all the features of leather, sun roof, Bose sound (which is the best) ABS, side air bags, etc. I use it mostly for commuting and now have 105,000 miles on it. The mileage is great (28-30 mpg) for work and 32 mpg on longer trips. I've only had one problem about 6 months ago it wouldn't start once in a while and would quit while slowing down for a light. Nissan sent out recall at the same time which fixed the problem. My only complaint would be the poor quality material of the seat which started cracking about a year after the warranty expired. Also the automatic shifting is like working a rubic cube.
Styling, gas mileage, and Bose sound system
Improve quality of interior leather seat material and make it easier to shift the car into and out of drive and park.
