My lumina is not in the best shape... when I bought it everything was great... however I never really took care of it. The 3.1L engine is very easy to fix. I got into a car accident, and totaled the other car, my Lumina started up, and drove away. I aslo had an experience with water, the water was all the way up to the bottom of the doors, and engine was partly submerged, it started JUST GREAT!!!! And ran awesome! However I have a transmission leak, and have heard that it is pretty common for my model Lumina.
