i have one of the rare w201 2.5td sold in 1987 (1 of 1200 I believe).

I has been in parked in the garage for the past year and I brought it out this past weekend. I think the new diesel fuel has done a number on the fuel system. The injector pump seals started to leak last year so I replaced the o rings and they no longer leak. I think the injectors are clogged. I ran 3 cans of diesel purge this weekend and it has made an improvement but it isn't perfect. It might be running on 4 cylinders not 5. when the car is running and I feel each injector firing, the #4 injector's 'ping' is much more pronounced that the other 4. It might need new injectors.
the tranny was professionally rebuilt a couple of years ago.

the car has no a/c and it is pretty uncomfortable in the summertime.

what do you guys think the car is worth? it runs fine but is pretty slow going up hills probably due the injectors.

i might just keep it for it's collector's value but I might be too practical for that!
