I do like that alot.. I bet it is impossible to find one! The w123's in my area go for around 2k. And for 2k you get near bullit proof reliability. Maybe is would make a good dd and I could garage the mach..
I used to own a 1979 280E , second owner straight from Germany. Inline 6. Bought it off my 6th grade math teacher... And I must admit - it was a fun little car to have. Got a lot people to look as you just don't see them that much.
(or at least not in the area of Michigan I was in at the time).
But I agree - keep the Mach, pick up a MB for a fun DD. Drop it on the ground an have some fun with it.
I could probably understand it if we were talking something with AMG on the end of it but an 80s diesel? I think I know of a nice black one here locally if you really want too I will buy it and trade ya for the mach.
