The bloke was from Swindon, it was a Satin Silver with the rear seats out, and a drive train tunnel set in. The rear was plastered with decals advertising his business, presumably in the Swindon area. This was mid 2004. The reason I approached him was I couldn't understand why his CTR left mine for dead on acceleration and when, when I was following him, why he was taking different lines and I noticed that the lift off U/S wasn't as evident. As for the conversion, being relatively new to the CTR at the time I just assumed that this was a known expensive mod, for the track. I spent a while myself trying to find out later (about mid 2005) info on this but drew a blank. I put it down to a one off.
