I have a 1998 C280 6 cylinder. I just bought it used from a friend. I did a search for the Flex Services and this site popped up. What I was wondering is, what should the A & B service cost? I was going to take it to a dealer but wasn't sure what is too expensive. Also, would it be better to take it to a shop that specializes in imports? I was reading through and you all seem to know a great deal about this so I thought I would ask. Any help at all is useful. Thank you.
