Hello there, Just bought a 92 325is for my son (his first car) and yes he is a bit spoiled. Its in pretty ruff shape but is driveable. I have not gotten the shop or owners manual for it yet so I have alot of unanswered questions about the car. If I could ask one, I have seen that a battery vent tube is supposed to be used? Is that needed ? Thanks, and thanks for letting me join in.
