I've got a 1982 Mercedes Benz 300D Turbo Diesel for sale. It's an automatic and has 220,000 miles. It runs great and has a professionally installed Greasecar kit.
The car has been very well taken care of mechanically. I have over $3000 in service receipts in the last couple years:
complete brakes all around (new hoses, discs, pads & reman. calipers)
transmission service (filter & flush)
rebuilt front end (tie rods, lower control arms)
four new tires
The car has a few minor body issues and a small amount of rust, but is better than most I've seen. It's an extremely solid and reliable driver and ready for another quarter million miles.
$3500, offers considered.
