I started my SCCA Production-category road racing career (such as it was) in an E Prod MGB. I had a tight network of Britcar-loving friends, including one who went through SCCA driver's school with me in his Bugeye Sprite.
I never finished last in a race, and I occasionally had a good dice in the MGB, but when I ran out of money and put the project on hold for a while, I kept the buzz going with SCCA Solo II in a friend's then-brand-new 1990 Mazda Miata.
My first time on course in the Miata, I took second in class by about half a second to the guy who went on to win the national CS (if memory serves...) championship in Salina.
My second time on course, I was stunned to see my times were about three seconds below anybody else in my class.
Naturally, it took me 17 years to buy my own Miata.
In the past few years, I've been jonesing seriously to buy a clean Spec Miata with logbook and two sets of tires, etc., and set it up for Vintage.
Why? I'm okay with mechanical work but not so hot with bodywork, and there's a much lower chance of having to bang out a fender in Vintage. Plus the scenery is gorgeous.
I'd paint it red, put on a white roof with a flip-up vent, run it on daisy wheels, and make it look like a BMC competition car of the SIxties -- maybe even have a British vanity plate made reading GRX 307 D just for the sake of solidarity with the Sacred Octagon of yore.
But seriously, in any class in which there's a sliding window for vintage eligibility that makes them legal, Miata is always the... you know.
