1980 300d turned over 800,000 miles 4 years ago, is now in the shed as a parts car but still drivable. I have a friend with a 1979 300d with 1,150,000 miles and still going strong!!

1984 300d turned over 400,000 miles about 3 months ago. Its a long way to the shop for milk & bread here (about 120 miles return trip).

1987 250td is only a baby 92,000 miles

I haven't had to remove a head or sump yet!! Give it time!
