This is a $700-900 job including the necessary alignment afterwards.

I've had my 94 C280 for over 8 years now. It has about 100,000 miles on it. I bought it with about 50,000 miles. It has been a good car but expensive to operate. Knowing what I know now I would probably not purchase it again, and would instead look for a 1996 or 1997 E320.
