Where I live--and I think nationally--there are a substantial number of guys who believe fervently in the older Mercedes diesels, especially the 1982-1985 years (with the W123 body), and the five-cylinder 617 turbo diesel engine. The problem is of course, that these cars are getting really old. The bodies seem to be wearing out before the engines.And the problem is often neither the body nor the engine, but the windows, A/C, sunroof, door locks, controls, instruments, seats, and cruise control. Are these cars only for (1) tech guys who love to work on cars themselves and (2) rich guys who can afford to take them to the shop every time something goes wrong? NOTE: under make/model, this site doesn't allow me to select 300D, so I put 240D, all that the model selection allows.
