I have 1985 300D turbodiesel in McKinney, TX. I got the car as wedding present 5.5 yrs ago and just love it (except when its giving me a trouble here and there). It only has about 230,000 miles on it and so far the worst thing that has happened to it was that the big bolt holding the harmonic balancer in place worked itself out one day.
After a tense week or so, a used harmonic balancer, seasoned German mechanic, and a new oil seal, all was ok.
My current issue is the right front wheel being out of alignment. -1.3 degrees of camber. Hopefully, I can find the resources to do this job on my own.
