I have a 300 e diesel 1995. First the MB dealer told me $350 to replace them. After I drop it off this a.m. , the service manager calls to tell me it's $500, then calls me back 45 minutes later to say that Glo Plug #4 is frozen and won't come off. Went on to say that they need my permission to brake it off but 50/50 chance that by doing so they could brake a coil, which would ruin the engine, which would amount to huge money. I told them not to touch glo plug #4. Manager said it will be a big improvement but not perfect.

Why do I get the feeling that they just don't know what they're doing, that perhaps they don't have a good diesel mechanic there? Maybe it's because he told me they were the original glo plugs when I have in my possession the records from the previous owner who, did, in fact, change the glo plugs 50,000 miles ago. Glo plug #4 was not a problem then.

This car runs beautifully once it is started. Plus after it is started once for the day, it starts right up. Manager at MB Dealer tells me I need new belts and bolts - $1,500 (which really means $2,500 coming from his mouth).

130,000 miles on my car.

I would greatly appreciate your opinions. Will get written suggestions from this Manager when I pick the car up next week.
