I bought my Altima used at 37,000 miles in 2001 and it's still going strong at 130,000, though it's needed some major repair. I've had to replace the alternator (at 75k), one CV axle and the other will need replacement soon, the switch for the power windows and locks, and the clutch a year ago. Those are the only $200 plus repairs done in 7 years though, which is a bargain compared to the repair work other models need in that amount of time. The interior doesn't hold up well however; the vents on the dash are popping up, a sun visor fell off while I was driving, and the speedometer sticks sometimes. The fabric is cheap and stains easy.
Acceleration is strong and gas mileage decent. A lot of range in the gears. Handles corners easily. Drives great in snow with the right tires. Paint's holding up very well against salted winter roads. Lots of room inside and it's pretty comfy.
