The MK GT9 is designed as a four-door sedan with tuner modifications, being distinguished by a yellow and purple paintjob, a body kit and spoiler, and purple neon underglows that light up at night. It loosely resembles the Dinka Chavos, and resembles more of an old Buick Regal.
The MK GT9 is considerably good in performance, possessing an excellent acceleration and a good top speed, while featuring average cornering (enhanced only if the player applies the brakes or handbrakes), and brakes that are only responsive at lower speeds as it results in the car having a longer stopping distance at higher speeds. The car's durability is low.
