Great little car. Bought it when it was 9 years old with 33k miles on it. Other than tires, gas/oil only thing I've had to do was replace a fuse and the bulb in the tail light in the trunk while putting 21k more miles on it. With $3+ gas it gets good mileage and is fun to drive. Think it's still on the origional top although the rear windows foggy. Have owned an MG, Austin Healey, Sunbeam Tiger and an Alfa Romeo; the Miata's as fun to drive, starts when it's cold, keeps you dry in the rain and is as reliable as a stove.
Easy operating top, reliability, roadster fun.
If you're close to 60 and need to change a fuse, get your kid to do it.
