Awesome pickup! My '94 isn't in nearly as nice shape cosmetically speaking.
You'll have fun in that. The 1.6 is revvy in comparison to the 1.8.
If it has OEM dampers on it, they are shot. They don't last beyond about 50k. Something to think about. Refreshing the suspension--bushings, dampers--on any NA Miata and installing some sticky tires can totally transform the car.
