Been for sale for ages.
I would be concerned if the build was done in Japan before it was shipped here.
At 430 bhp he defo should have had a lot of internal work done, plus you'd expect to do the brakes, suspension, clutch and bigger than standard rims too.
IMO he's selling it cheap as he bought it cheap off some independant and therefore is selling it relatively cheaply. If he had done it himself he would be proud of all the specific upgrades that the car had and not just list it as an APS TT zed and then prattle on about supercar performance 190 mph top end speed......all smacks of someone who didn't do the work themselves.......
