[QUOTE="mkarkos"]I barely got home last night. I need to get a new battery for my M5. Does anyone have any suggestions.[/QUOTE]
If you want a battery that fits the battery box correctly, look for a retailer that carries Douglas Batteries. Douglas Battery is the company that supplies BMW, Porsche, and Mercedes in the US.
Interstate or Gould are two other companies that might have a fitment.
Sears has a DieHard International (GRP 49) that fits perfectly - 36 mo. full replacement warranty, 100 mo. prorated warrnaty - $109.99 plus tax here in Houston this week.
Thanks everyone for your input. I checked the curent battery and it is a motorcraft? Who would put a Ford product into a BMW? Anyway it wasn't the battery but the alternator.
