I just got a '91 318 TBI with 250k. The R12 a/c still blows cold. It was garaged when not in motion, so it's in really good shape for the miles. I'm actually thinking about selling my '01 R/T. I put colder plugs in the '91 and turned the timing up some. It actually seems to have some decent midrange power. The main thing I'd change about it at the moment is the rear end. It needs a sure grip, so it'll actually move on wet grass and such. Once I find a couple more R/T wheels and caps, I'm going to put them on it.
