I got a miata figuring I would drive it for a summer and sell it and as it turns out, they're a hell of a lot more fun than I thought. They're reliable as long as you take care of them to a minimal extent. They hold resale value and you can pick one for pretty fucking cheap. (Got a low km, non-rusty one for 2800 cad)
for reference I've put 50k kilometers on mine, and have had to spend under 1000 to keep it on the road. I also abuse the shit out of it daily. that and you can scare the fuck out of people hitting corners so that's always a plus right?
