I found someone who has a 1982 240D that has 30k miles on the rebuilt engine.

I do not care about speed (well I do, I dont want to get into an accident because its too slow) but I mean I am willing to go from a 300 turbo to a 240 non turbo.

Anyway, the guy is asking "between 2500 and 3000" dollars for this 240D - and said that he may be willing to trade my 300sd for it.

I would advise you not to buy the 240 D! Keep your 300sd, but send me the name and phone number of the guy with the 240 D, so I can call him to see if I might buy it!
