Phil Here, Thanks Sun Guy for the info. I called MB Road side assist. they wanted 377.00 to come out and replace my Battery. I told them no thank you. Then I priced a Interstate battery and when I told them it was for my SL the quoted 378.00 for just the battery. What gives??
The Battery in the trunk of my SL looks no different than any other " Long " Car battery??? again, What gives, I hate to be taken just because I drive a 500 SL. Any other suggestions?
