Since I've gotten a job, my budget has increased a bit, so I have more options.
I'm currently looking at a 1990 Audi Coupe Quattro with 200,000 miles on it for $2500. Unfortunately I have to work all weekend, so I can't go look at it in person until next weekend. The car also needs a new power steering pump, and the pump is $350
Or I can just save my money, wait until July-ish when I head over to the Portland, Oregon area, and buy something nice, because finding a nice car I want in this area sucks There's always plenty of reasonable priced BMW 3 series in the Portland area, so I could give that a shot...
There's also the option of getting a lightly damaged Audi and rebuilding/fixing it, though I'm afraid it would be quite costly depending upon what the car is and what kind of damage there is...
