anything I should pay particular attention to. All I know so far is that it's an '83 and it runs.

...You never want to buy somone else's problem. If I were you, I'd take a pass.

went and looked this afternoon and was pleasantly surprised. Car is a daily driver, ~ 112k on the ODO. Original paint, a couple of small rust spots, cracked dash, torn driver's seat.
E brake doesn't work, diff's not locking (owner claims it's the solenoids and he has the parts to fix, engine idles smoothly, no smoke, a few small oil leaks. Suspension pretty tight, just a little wandering. Needs tires, has G60 brakes in front. I really was hoping to not like the car, but now I'm seriously considering it. I think I'll take it to local Audi dealer for a lookover.
