This is an awesome little car. If you don't have fun driving it, you may very well not ever have fun driving ANY car.
Handing is nothing short of incredible. Fairly quick (high 14-sec 1/4 mile). Feels stable and solid even at high speeds. Awesome track & autocross vehicle. Turns heads. Take it to the twisties and have a blast!
Larger intercooler: the tiny one looks like a bucktooth! Higher redline: Standard Miatas have a 7K redline, and people who have turbo'ed a regular Miata are not having problems with a 7K redline. Cruise control: although it's not really a highway car, cruise control would have been nice.
