I guess your right... since i just found out that there are 15 battery that is attached to a 2008 M3 in the computer, i was quoted one with low AMPERAGE and CAA. i looked at my battery and cost $210 which is the 90ah and 900 amperage... which is still good enough was hoping to pay $135 though... LOL
anyways cant complain cause the newer battery for 2012-2013 cost around $510 its weird how every year has different battery part number.
