i think those are a great looking car Keith, my dad had one, i don't recall what year it was though, i was young myself, i do know that he spent a fair bit of time on it, apparently the carbs are tough to keep tuned, if the car was driven anywhere near salt roads the frame etc would take a serious beating, in some of them i think the voltage regulator was housed up in the fender well, a rock hits it and dead engine, stuff like that. Having said all that they are pretty for sure. I know of one guy in edmonton put a toyota or something or other engine in his and other parts, runs good! LOL Here is something i found. Hey!! Miata's are a great little car.
