The only other thing I'd suggest you have a look at is the condition of the lower control arm bushings. These cars chew them up. When I replaced them on my '94 C280 the job cost me $700 Cdn including the alignment, plus taxes. That was with the dealer, but the dealer was the best price option I could find. The cars also seem to go through ball joints, but they aren't as expensive as the big stuff.
