OK so if the logbook says "Escort RS Turbo" thats it. So even if a guy changes his XR3i into a RS Turbo and it's all like for like the DVLA can never change the logbook from say a car showing originally as a XR3i to then showing as a RS Turbo? Is there is anything on a RS Turbo that cannot be put on a XR3i no matter how good you make it?
