Been trying to remember more about this one, having looked at reg no, this is the number that was once on Jerry's current car, hence the reason the guy has it adverised as a Tomcat, cos that's what the log book will say, that number was also once on the ABS Beneton style demo that was featured in Which Kit when drinkell took it over, from what I remember the chassis was brush painted in silver hammerite (didn't look too pretty) and those plates were put on it, so it hasn't been SVA'd, hence the dash
