Well I can't think off the top of my head any other british cars that appeared in GT4, is 4 door, weighs under 2 tons and hasn't been mentioned already....
I'm sorry to say but I've scanned the GT4 car database over and over and there aren't any other U.K cars that are a four-door, under 300hp, weigh under 2000kg/4409 pounds and that have a sprint of 0-60 over 6 seconds.
no i didn't, i said there are different versions of said car, it's under a different manufacturer in the usa version of the game. but the car i'm after is the british version of the car
