A good price for a 1993 geo tracker should be anywhere from 1000 to 2500 but I would make sure that everything is working fine since the vehicle is older. You can go online and check the kelly blue book value to get a more accurate estimation as to its value.
It is hard to determine a fair price without knowning the sub-model, features, etc. However, I would say a few hundred dollars to a thousand at best. It determines if it is a solid vehicle or not.
i think a good price for a tracker that old would be around two thousand dollars if it is in stellar condition. if it is in moderate condition then somewhere around a thousand may be a better price.
A 1993 Geo tracker with 100,000 in good condition has a book value of $2,900. The actual value of the vehicle can be better determined with the actual mileage and additional equipment/options on the vehicle.
