well the car itself is over a 100grand msrp and they;re hard to find so you'll probably pay a premium on top. the kit itself im guessing can cost no more than 30grand. more than that and its a rip off for sure. imo the tuning was the hardest part but it seems they have things flowing nicely. ill tell you what though, i wanna see a fully modded supra pull up to this guy thinking hes got the best highway monster ;)
