First time on this thread in ages, just saw BoostedBumps new MX-5, beautiful car!!!
I worked out a simple build on one, convertible then the hard top car, same color as yours or gray would be the pick.
Either the base model of of the vert or mid model with hard top.
Base model with after market LSD, Ohlins coilovers, sways, WW BBK, 17x9 wheels, intake, exhaust, tune, mild aero, etc, sell what is not used, around $35k total, approx 200WHP.
Hard top does not come in base model but build would be the same and around $40k.
Then I started looking into engine swaps
