This car runs and drives and it's a sleeper…and most importantly – it is FAST. I have had 4 Fox-body Mustangs, and none of them would hang with this little Monster.

The individual I bought it from had set it up to use as a drift car. He bought it from the guy who built it. I can provide you with the builder’s number for more info.

It could easily be tuned for street, drag, or drift. Supposedly the builder used the kit from Monster Miata.

I am located in Springfield, IL.
