Have 145,000 miles now, still getting at least 28 mpg at best 32 mpg. Brake rotors finally gave out at 143,500. No major problems or concerns ever! Still flies through emissions tests every year. Not looking to get new yet, but will go Nissan again, and again...
Peppy 4 cylinder that gets great milage.
I think Nissan has taken care of them with the new Altima!
