I race a metro in MG metro cup and i believed my car was one of the original dunlop metro gti cup cars. Although having done some more research it looks like my car is either an original that has been reshelled or a reserve car as its not got a sunroof. It definitely did some racing back in the early 90's and was built by rover as a purpose built race car. My reg is G48 JOF Thats about all i know, i'll attach a picture...
