This car a been extremely reliable for the entire time I've owned it. It now has 215,000 miles, and has only a little more than maintenance done. It did have to be repainted, due to peeling, which is fairly common on white cars from that time period (not just Mazdas).
I like the way gauges and controls are laid out. And of course, it's a rotary car.
Put a Racing beat exhaust, K&N air system, use an aluminum turbo II hood as a fresh air hood, and if you're feeling froggy about it, do the injectors and fuel pump. Zoom Zoom!
