I am looking for a battery replacement for my 1997 M3 sedan (E36.) I think someone recommended the Sears Optima Red Top but I don't know which one or if this is a good choice or not. How much is the official BMW battery? Also, if I use a Optima, will it fit? Anything special do I need to know about installation or even removal of the original battery?
