That little test proved out a lot. The motor runs, the clutch works, the transaxle works, most of the electrical system works, cooling system works, exhaust, steering, oil, suspension. It shifts. Get the brakes done and you can expand the envelope and take it on the road. Figure rebuilding all 4 calipers and the master cylinder and replacing all 4 hoses. You should do the clutch hydraulics too (if it's a 5-speed). Next time you get the motor hot you should replace the oil and filter.
