Cool beans, Ben! I've driven a few miatas and I know what all the hype is about! They really are a lot of fun.
I know there's a HUGE miata group in CO. Grand Junction has a cool shop called "Flyin' Miatas" and they have a great website, too. IIRC, there's a lot of maintenance and performance info on that sight. Lots of performance parts, too.

My Miata-related advice to you: get a cute dog to ride shotgun and you'll be the ULTIMATE CHICK MAGNET.
