After about a year's daydreaming, idle searching, then more serious searching, I found my unicorn.
My daily silver 2006 NC Miata Grand Touring was getting long in the tooth, and after having some electrical issues around the #2 cylinder (that came back) I decided I wanted to move on from that specific car. It had rolled over 200,000 miles and the clutch had reached the point of obnoxiousness. Likely a full refresh of the clutch hydraulics would solve the issue... but I was getting tired of the idiosyncrasies piling up.
The unicorn was a 2009 (first year of the NC2 updates, with improved driveline and interior ergonomics. I've been driving NC's since 2008, first with a 2007 Sport model, followed by the 2006 Grand Touring. Both have a door mounted cup holder that digs in to the driver's thigh. The NC2 recesses it and smooths out the door panel. From 2009-2015, with the run of the NC3, only a few hundred were made in Competition Yellow. I've seen a few of these around my work area and it turns out one was available at a dealer for what seemed to be a reasonable price just as I was getting unhappy with the silver one.
