This car looks very nice, but is a mechanical nightmare. Every sensor on this car starting going bad at 50k and catalytic conv at 80k. Nissan said cat ruined engine and needs a new engine (bad placement of cat). Lots of other people with same problem...would not recommend this car. Also own a Infiniti G35...no problems..think the problem is with set up of the Altima. If your under 80k Nissan will only fit cat, not your engine :(...They know about the problems but don't care.
