Mercedes has a habit of insisting on using their expensive products. Aftermarket sales can be so lucrative in the automotive business that I wonder if car sales are simply a loss-leader for aftermarket service!
If we can get hard data on issues like this coolant, perhaps everybody on this board can save a few bucks and have the convenience of buying from somewhere other than the dealer. Where I live, compared with the local auto supply houses, the dealer is inconvenient to get to and has limited hours.
Jay, could you please expand on the research you've done?
