I've got a 1970 220D I've been driving for years. I have own 200Ds, 240Ds, 300Ds, 300SDs, and 300SDLs, etc - the 220D beats them all for reliability and endurance. If you can find a rust free (ha ha ha) buy it! (or email me and I'll buy it). I have seen clean 220Ds sell for upwards of $4000.00. I would spend around $2500.00 for an exceptionally clean one - personally inspect for rust, do compression hot/cold testing, etc.
