First of all, my '82 300D must be geared significantly different from John's. This would make an interesting thread, such as "What speed do you register at 3000 RPM?" It would be interesting to compare different model years of the 300D and 300SD.

On the surface, the car seems to be a good deal. I'm not sure the tint is legal in my state......

In regard to the issues with the car, these are probably relatively simple compared to something with major engine or transmission problems. I'd have to wonder if the car had been properly maintained, of course.

Small Oil Leak - maybe the turbo oil return seals.
Trans Pan Leaks - probably a new filter/seal is in order anyway.
Ignition Switch - replacement item.
Glowplugs - As you say, probably the GP relay.
Wheel Bearing - Go ahead and do both sides.
Radio - You'd probably end up going with your preference of aftermarket radios anyway.

This is really just typical little stuff that is satisfying for the DIYer to fix. At $500-$600 for the car, it seems to be a good deal. If it were close to me I'd certainly consider it.

Here are some other things I'd check, now that I have learned a little more about the 300D.

- Pull up the floor mats and check the floorpan for rust.
- Open the trunk and check the inside of the fenders and the spare tire area for rust.
- Check the condition of the rubber suspension parts. Someone who has kept up with maintenance should probably have gotten at least some of them replaced by now.
- Check the dastardly plastic radiator for cracks at the hose connections
- Check the condition of the axle shaft boots (shredded = bad)

These are rather quick checks on typical 123 problem areas that could be expensive to repair (although not unreasonable when you get the car for $600.

I'm sure someone would tell you to check the compression on all the cylinders - but not an easy task. I wouldn't let anyone rip my injectors out to test compression either.

What else is good to look for on the 123s?
