Yeah the one I saw was definitely white, might have had a red chequered roof, not too sure though. Should have got the last 3 letters of the reg, but was too busy looking at the car to be honest!
You know, I swear I've seen your car parked down Harcourt Terrace in the past. Either that or someone else has a very similar motor.
I'd be more noticeable with my old Yellow Bravo HGT, otherwise I'd say keep an eye out. Lot's of Silver/Grey GP's about.
