Many thanks for your response! I do feel better knowing that their labor quote is on target. I have had excellent service from this dealer in the past, but was expecting a much different number of labor hours.
Yes, I am having a 4 wheel alignment as well. On that subject, I have a good question for you! With the E55 suspension installed on my E300TD, should they use the the alignment specs for the E55 or the E300TD- or perhaps are the caster/camber/toe specs the same for both?
