I've decided to finally sell my Miata. I'm looking to free up garage space this winter and then hopefully replace it with an ND Miata next spring. My ad on craigslist is pretty detailed, so I won't retype everything on here: http://worcester.craigslist.org/cto/5246894789.html
It's basically a well sorted STS car that is now illegal in STS because of a few things I've deleted. It's technically in DP due to the gutted HVAC and missing windows. If you are planning to autocross it - you'd be most competitive if you put some of it back together and ran it in STS. If you're not interested in being competitive in SCCA autocrossing - it's a RIOT to drive as it sits.
I have been using my Mazda 2 for the last two years so the Miata has pretty much only been used for fair weather daily driving since then. I've used it for a few events with random clubs with loose classing and it has hung in pretty well with some serious cars.
