I believe it was driven then by Peter & Hilary White, Y10 gurus at the time.
Perhaps sold to Trevor Nicosia?
This is where it gets complicated!
First of all, I acquired the engine from that car. That went into my Y10 Turbo, the one that later became the Yntegrale. When the Yntegrale conversion started, I sold the engine to Peter Dietsch and helped install into his Y10 Turbo. Things go full circle, I acquired the Dietsch Y10 earlier this year
Around 1998 or 1999 I boughht the rest of the RAC car from Peter and Hilary, it now had a GTie engine in it but not running. I took the GTie engine out, replaced with one of the many Y10 Turbo engines I had in that era and started the conversion to race car from rally car. After a few months I realised I was taking forever to get the car race ready so engaged Scheldt & Pettet in Harrow to finish the job. They found the shell was not as straight as hoped, different wheelbase each side courtesy of its hard life as a rally car. WQe kept the roll cage, doors, front wings and bonnet and scrapped the rest (sorry!), then put the cage into yet another Y10 which I had lying around. Kind of explained my first season colour scheme, half dark blue, half yellow!
The cage still has the 1993 RAC scrutineering stickers on it
