I have a 1988 300TE. Overall cosmetic condition is fair to good. It was a basket case when I got it for $700 and I put about another $600 into it so far with me doing the work. It is at least drivable now. It has 187k miles on it and there is still a lot to be done. I'm trying to decide whether or not it is worth sinking more $$$ into. Here is the short list of what else needs to be done.

At least 1 lifter replacement
Rear differential replacement
Drive shaft flex joints
Shocks all around
Rear bushings (it sways around a little)
Climate controls non functional
ICV and hoses
Complete emergency brakes (everything is missing)

The cars intended use will be a daily driver averaging 330 miles a week. Give me your general opinions. Thanks
