as far as batteries, I just bought an interstate MTP-93

ran me $135 from the interstate shop and they installed it (warehouse not local chain); they tested my old one and it was still producing 350CCA and 12.5V, told me it was installed 3/2000 which means that battery lasted 10 years and the BMW battery only lasted 3 1/2-4 (9/96 build date).

I added water to the old battery prior to swapping it, it saved it a little (was reading 100CCA and 11.5V immediately after turning off the car). don't know exactly how much water it took, probably 1/8-1/4 of a gallon. the interstate you lift the handle and then pop open the rectangular piece under the handle to expose 3 cells (each side). mine was quite low, all but 1 cell was exposed and 2 were completely dry.
