The MK GT9 is a car only available in Grand Theft Auto: Chinatown Wars.
It's design is like a tuned sports car. It has a yellow/purple paintjob along with a body kit and spoiler. It resembles a Ford Escort Cosworth but the only difference it the Ford escortcosworth was a liftback the NK GT9 is a sedan
Being a modified car, it is really fast. It can accelerate quickly, but the handling is quite poor, with lots of understeering.
