I hope some of you are joking. While a nice condition s13 can go for a few grand, it doesnt mean 2k wont get you a decent car. I have bought all my s13's for under 1500, while some were junkers, some were gold on wheels.
From what I have noticed personally, the market fluxuates, and there is usually a prime selling time, and then a prime buying time. When they hit hte market, they all hit at once, so keep your eyes and ears peeled, check other forums too....floridadrift.com, sfldrifters.com, etc. Seeking a car will probably run more than running into one. Its definately not a low ball offer for a decent s13 anyways. Good luck.
