So about a month ago I bought a 1979 300sd for 3,500 that runs ok and has a great interior, but no running A/C. I was wondering if I paid what its worth and why I don't see that many more people on this forum with the same car. All I see are 84-87 300d's, is this because the 1979 300sd was more rare, or just more crappy and not worth the time to fix?
