In my experience MB does not offer 5 year plans covering 50,000 miles.
I bought a premium plan for my SL500 from DaimblerChrysler - $2,480 for 5 years and 50,000 miles. During my first visit to the dealer after I bought the plan MB identified $4500 worth of warranty issues:
Replace both front strut arms
Replace both engine mounts
Replace psi pump
Replace electrical outlet on gearbox
Replace left rear shock and service ABC
The claim was processed within 24 hours and it cost me $100. I still have 46,000miles to go and 4 years and 8 months of coverage. My mb service rep had nothing but praise for the interaction with the insurance company. 24 hours turnaround to get it PAID and I drove off.
Sure they do not cover brake pads, door handles and trim. I would be surprised if MB does.
Check this forum you will find a lot of folks that reference the warranties provided by Michael. I do not know the guy, just used this forums advice. I am not saying do not buy the MB warranty. Do your homework and make your own choices. I am just a very satisfied customer that will probably buy an extended warranty for my GL450 and ML350 from the same guy.
BTW MB wanted to charge me $500 for 16 spark plugs. I bought the very same 16 Bosch FR8DPP33's for $100. Makes you think doesn't it.....
Here is Michael's information.
