Bought car used from friend noticed fog in the fog lights he said "I've replaced the head lights because they had water in them now they're fine. The fog lights have always been that way too." I have now owned the car for 16 months. The head lights are fine but all other lights fill with water. Now I have to take apart the rear end and shake water out of the lights every 5-6 months to keep the water below the bulbs. I've already had a reverse light go out because of water. Many other problems with car too speedometer, lighter, roof trim. Total crap don't buy 2000 or newer Impalas you'll regret it.
