We have one, it's pretty much the same car..lol. Everything on the engine and trans is the same (so same issues), I don't know about rust stuff though. It's rockers are in better shape than my GP's but it's got peeling clear coat on the hood. Just did the water deflector on the impala because we were getting water on the passenger floorboard, so really, it's the same car. I think the window motors are different since they move a lot faster than my gp's.
