I've put just over 2K on mine since I got it... it's now up to 503440.
it's got issues to be sure, but it starts instantly, doesn't excessively smoke or rattle, and it handles well. I'd love to know the entire story of the car, but the service booklet in the Glove box shows a few hundred thousand miles of service... I'll check in on this thread every 100k or so...

My 1984 300CD has 336,000 miles. I got a photo as it rolled 1/3 of a million miles!

i have an 82 300d with 150k just got it
