I think I would have been steamed too. We have had to alter Interstates list price to sell below MBs list price. That must be some roadside assistance cost on that battery. I think MBs list on most batteries is only a little over $100.
I forgot that Continetal Mortorcars was in your area. There are at least one other Continental Motors in Florida and numerous other combinations nationally.
No problem, I just felt it was important to clear it up.
