This looks like its gonna be a good option for 90-93 Miata's. Estimated price $700. I love a free market !

2013 Red Miata Sport
2006 Winning Blue Miata
2000 Red Miata
2011 Red Mazda2
2015 Smart Electric
looks like its already out with the exception that its a MS1 instead of MS2.
Pretty good deal though.
