Headlight went out, no big deal. Just VERY hard to replace. First time it has ever taken me 3 hours to figure out how to change a headlight. Also, in the process of trying to change the headlight, the retainer ring managed to break, had to wait a week for the GM Dealer to order the part.
Overall, this is a fairly good vehicle. I haven't had too many problems with it.
The deal with the headlight caused me a bit of headache, bit, but nothing to really complain about.
The dash seems to be real loose. It shakes and rattles very badly when slowing and stopping. Also vibrates to annoying levels at a cruising speed of about 78 - 82 MpH.
To replace my factory radio with an after-market stereo required a special wiring harness that cost me 4 times as much as a normal wiring harness. Not to mention the factory stereo is still connected to my cars electrical system via the specialty harness, as required, something about engine components/sensors being routed through the radio.
Car shakes and shudders violently almost when slowing and stopping. I believe it involves my braking system, however I have yet to check on the problem.
Overall, the interior is well laid out, except the window handle knob that jabs my knee if I try resting it on the door when driving long distances.
Plenty of trunk space, the cargo net comes in handy.
I have a (1997) Cavalier, and have also experienced problems with the dashboard vibrating... I removed it and tightened things up, and it's less of a problem now. Anyhow, if you go to an auto parts supplier you can get a tool which will allow you to remove the window crank, and you can reposition it so that it faces the toward the front of the car, when the window is all the way up. I did this, and it's a big help.
I don't understand why, if you are having problems with vibrations, you haven't taken the car in to be serviced. the shaking above 75 sounds to me like an alignment issue, and the vibrations when stopping are most definitely a result of warped rotors, which, if you read the other reviews, these cars have a problem with. if you get those two issues taken care of, which won't be very expensive, you would have a great car.
You got ripped on the stereo my man. There's nothing routed through the radio other than the door chime curteous "ding" when you leave your lights on by accident, and/or Onstar speakers. All that crap about the engine not starting without it or running funny is a load of BS.
I also got the harness on my 2000 cavalier... it is necessary to have, the factory deck holds lots of information, not just door chimes, it has information about the dash stored in it, it is nearly impossible to install a deck with out the T-Harness, they guy above is clearly dreaming up a story to make you feel dumb about buying the harness (by the way I ran my first deck without the harness and it caused too many problems so I went back and got the harness, I work at a Visions store as a technician, so I thought I could do the install without it as a test to see if its necessary, however I was wrong, as is the guy above this comment.
