I had this car for about 8 years now, no major problem except 1.5 years ago the head gasket was blown. I rated 9 for build quality because the window rubber seals on front and back wind shields deteriorated. The weird/rough shifting feel from 1st to 2nd gear (yes it's an auto). Some electrical problems such as front speakers didn't work, CD player laser lens gave out. It didn't really bother me much since I use tape deck for the mp3 player. Overall, this car needs a bit more power.
Ride height at stock suspension isn't bad. Better feel when you lower it with aftermarket suspension setup. Engine bay is easy to work with, lots of room, and the interior design is great for the 90s era.
Nissan should bring back 240sx successor. The Altima 2dr isn't ideal in my book (no offense to altima owners)
