I've been advised by a very good (but top dollar) MB shop to replace my 300E's rear control arms, rear differential mounts, and tie rods.

Are those basically just nuts-and-bolts jobs that a half-decent (and much cheaper) garage should be able to get done for me w/no problem, even if they don't have experience doing that work on MB's?

The difference in price could be substantial, but I only want to pay to have it done Once.

The first shop I definitely go with when something requires extra precision or particular Benz knowledge/experience. Is this one of the jobs that needs the experienced hand, or can I save the money if the cheaper guy is even reasonably competent?
