I've had my Impala for 2 years now. bought it with 9,000 miles on it and it now has 38000. I've had many problems with the car SINCE i bought it, and it doesn't look like it's going to stop...first thing, at an unbelievable 17,000 miles, the tie rods and ball joints needed to be replaced. Next was the actuator for the trunk release (took 1 week and 3 actuators to get it solved. there's a noise that sounds like a vacuum leak that the dealers cant figure out whats causing it. Then the tire monitor system. Now there's something wrong w/ the A/C (common problem) that's making it click at random. The heater doesn't work...I've taken care of it, and it was a dealer car before me.
it is fun to drive, remote start, and the fact that it probably will run forever. it will run crappy with a lot of the electrical issues, but it will last.
