oh i know lots about the engine/car had it for years no wrecks, its a sedan (so no spoiler), 3100 v6, its in great shape not even 150k miles.
1. the only problem when it runs is once in awhile it loses power around 55mph but that seems random
2. whenever i turn on the heat or a/c its like the vent is on it blows air through all vents easily with no problems
3. only problem with rear of car is a few cracks in bumper but thats from age. i know its from age cuz i do bodywork, i suck at mechanical things but i can make it look pretty
