The experts have given you good advice. My experience has been climate control is very tempermental and the servo's are expensive to replace.

All in all, between my father and myself, my car has had no issues, except the climate control, in almost 25 years of driving. Mine has 173,000 miles and runs like a dream.

Of course rust is a major issue up north and past maintenance is key as well, but if the owner maintained the car, you will have a great time. I love my 1977 300D.
