I would like to do a survey of E55 W211 owners who have over 25,000 and 50,000+ miles on their cars.

What kinds of problems have you encountered?

Have you noticed a fall-off in performance?

Has anyone Dynoed their cars to determine if there has been a deterioration in horsepower with age?

Is there something the rest of us should know that might justify buying an extended warranty?

Thanks in advance for responses.
