I'm not a big fan of Miata's BUT I know they are a decent little car and can be made to handle supurbly for not much $$.
When I say I'm not a big fan...I mean for me to drive...I'm not saying it's not a good reliable car at all.
Less than $20k for that car is a bargain period...nice purchase.
*edit* Just realized how "old" this thread is
and didn't read all of it. I still say what I just posted above BUT must also say...nice job with the upgrades...nicely done !!
