I've come to find that Miatas are by far the most rewarding cars to drive fast, even if you aren't at the top of the time sheets. The low weight and center of gravity (and open top) make you feel so connected and it takes a lot more effort. And with how cheap you can buy them, you can put more money into it later as you see fit like doing an engine swap like an SR20DET - it's been done, aftermarket support is there, easily holds up to 400whp on stock internals (which is more than you'll probably ever need in a Miata).
Why people find it necessary to shell out ridiculous money on a track-only car before any modifications is beyond me.
Stop putting stuff like painted reflectors and premium package in your signature. You're embarrassing.
