Wow what a trip :-),
Well my mom in law got the diesel bug from us (we use biodiesel and converting to SVO). So her dream car is 300CD turbo. She found the ad in the paper and I went to check the car for her.
Dealer got the car in an auction so no records. He was Mercedes mechanic in the past so he knew his stuff :-). When I came to the dealer lot I found him working on an odometer

, Not the CD though :-).
The car apparently didn't drive for few years, yet he said it was no problem to start it, he replaced the oil pan and of course the oil, and battery
The car started without a problem yet wasn't smooth when cold later on it got better. Checking blow by I polled the tube that goes to the air filter, no blow by. Well off we went for a test drive, I floor it the engine gets to 3500-4000 RPM no problem and no smoke ALAS the car barely moves.
The transmision had no problem to engage within less than a 1 second.
Can you explain that ?
Of course all the weather strips need to be replaced.
The asking price was 4000 later he was willing to take 3000
What do you think about it ? LOL, to walk to a dealer and see how he "fix" the odometer
