1990 Spec Miata For Sale

Jonathan Davis

Recommended Posts

I am selling my 1990 Spec Miata. It has been a fantastic car to get started in. The car was originally built and raced by AIM Tuning. I bought it from the second owner at the end of 2010 and have raced it from 2011-13. It has been very reliable and performed well enough for me to run near the front in the NASA Great Lakes region. The car has had no major crashes that I am aware of, but it has a few dents and wrinkles from years of Spec Miata use. I have maintained the car as meticulously as I could. Put in your safety gear and transponder and it's ready to race.


$8500 or make offer.

I am in the Cleveland, OH area.

I am willing to deliver the car within a reasonable distance and I can assist the new owner with corner-weight and alignment if local.
