Well my mom's car is a CE110 Sprinter. A very reliable ol' gal she is too. The car I mean 217,000 km on the clock with one engine re-build at 180,000 km and she is still going strong. Absolutely no under-compression or any sort of problems. You see, it all depends on your luck at finding a properly maintained diesel car and then taking care of it. If I were you I would do a re-build as soon as I buy one so at least I'm sure of my engine. Any car would start giving you problems if you don't maintain her properly. Quite an economical car too. Full tank of premium diesel (40l) gives me a mileage of about 600 km = 15 km/l. I run a K&N cone type filter as well.
A good buy if you manage to find one in good order. Hope this helps.
