I bought my 98 Altima in March 2001 with 30,000 miles. Now it has over 200,000 miles! I've had almost NO problem with this car either. I had to replace the alternator at 120,000 miles and the the CV joints at 150,000 miles. The car has never broken down, and has made several long trips to New York, Miami, Orlando, and Atlanta from Tampa Bay. About 65% of the miles are higway and about 35% are city. It currently runs strong, just as it did when I first bought it. It does burn some oil (1 quart every 4,000 miles) and it's a bit slower then it was 170,000 miles ago. I don't maintain it as good as I should though. I change the oil every 5,000 miles.
I love the 150 horse power engine. It honestly feels like a small V6! It cruises along at 80 mph perfectly.
I wish the exterior looked better, and I wish it got better gas mileage. It gets 28 MPG highway and 22 city.
