No I don't see that, I see MB supporting the old cars by still carrying the parts, and being able to get pretty much anything for these cars at a reasonable price. Is GM or Ford doing that? I can walk into a MB dealer and get anything on my almost 20 year old car overnight if they don't have it in stock. Try ordering anything for my dads 10 year old Ford and it is an ordeal. Ford doesn't make it can't get it, go buy a new one is their line. If its more then 4-5 years old it seems most American and Japanese dealers can't get half the stuff.
If they are fixing prices they are doing a pretty bad job of it, ouch $4.20 for a rubber wiper cap hurts, ouch.
