Has anyone used a battery other than the one specifically called for? My son's 94 325is is need of a replacement and the few auto stores that carry the "proper" size unit want $125 or more. I haven't gone in yet to measure the battery and see if others fit, but it's hard to believe that another model for a "normal" car at a more reasonable price wouldn't fit. Just trying to save the kid a few bucks!
Any info is appreciated. Thanks!
