looking at 84 turbo diesel

[DaveH]

I'm looking at a 84 turbo diesel old style Mercedes, the round headlight type. As you can tell I'm a newbie with these cars. It's a sedan, 5 cylinder. The hood is rusty and missing the insolation. The AC is broken, the owner says it needs a compressor. The dash is cracked. The paint, sky blue?, is faded. The motor runs ok, a little rough but it wasn't warmed up. The seats are good, and the body seems good, the only rust I saw was in the holes of the running boards, (does the jack go into these?) and the bottom inside of the the doors. He's asking 2200. He just drove to the curb last night! What should I look for, is that a fair price? Does this car have an oxidizer trap? Cast iron head or aluminum? 198,000 miles. Will over heating cause the paint to peel off the hood?

Thanks in advance for any info.
