Those were my "between job" unemployed days. The car had 105k miles and I put on new brakes, shocks (KYB AGX adjustable) and a new clutch, plus had the transmission rebuilt. Then I was set. It looked and drove like a new car.
But, during my normal commute to work (new job) one day, the tranny let go (I think it was a screwup during the rebuild) and everything was again reduced to dust. Since I was too broke to fix it and had just started the job, I had to sell it. I hated to sell it since it was in showroom shape inside and out - not a scratch, perfect leather, power sunroof, etc.
Good GVR4s are worth about $5k. 100k+ miles is the norm but not really a big deal. Find one that has been well kept and has little or no mods. Mods by an experienced DSMer are usually fine. Just make sure it's got a recent timing belt, tensioner, and water pump. The transmission's weakness is the syncros; make sure it shifts into 2nd and 3rd easily.
There are only cosmetic differences between 91 and 92, most notably the rims and the tail lights.
