I purchased this vehicle used about a year ago, and it has all the upgrades that a 99 Altima SE could have, plus leather interior.
It has 175,000 miles and I have no issues with the engine. The steering wheel does not shake and it feels a smooth ride.
I also have a manual transmission, and always recommend purchasing a used car with manual transmission, because they last longer.
I am extremely impressed with the reliability that this 99 Altima has, and I am expecting it to go way past 200,000 miles.
My advice is take care of your Nissan and it will take care of you. This car in 1999 was voted JD Power and Assoc Motor Trend car of the year. It's unfortunate that some of you guys had problems with yours. I went shopping for a reliable Japanese car and compared it online with 99 Accords and 99 Camry's. Consumers and car magazines voted 99 Altima higher in reliability than those two, and better value for your buck!
