This car just rolled over 200,000 and still runs great.
Transmission started slipping at 185,000 miles so had it rebuilt since everything else about the car still seemed near perfect.
Replaced front brake disks around 150,00 but this is expected normal wear.
Balance wheel on front of engine (drives all belts) broke from fatigue at about 190,000. Perhaps it got damaged during transmission overhaul.
Currently the engine is noisy for first couple minutes after cold starts due to a cracked exhaust manifold, but as it heats up for a few minutes, the crack closes and the noise goes away.
It is hard to believe this car runs perfectly and has never had a tuneup. It has over 200,000 miles on original spark plugs. I change oil and filter every 5000 miles and it is always full and oil still pretty clean.
Body integrity is good, nothing has broken or fallen off. Still has original exhaust system. Current set of Michelin tires have over 100,000 miles on them. My secret to long tread wear is over-inflation. I run about 36 PSI in all 4 tires and check them every 2 weeks.
I have been so pleased with this car that I just bought another Altima, a 2007 model.
