Hi Phil,
I think they were looking at 0verall neatness under the car considering they are all driven on the track and road, as well as exhaust systems (sidepipes,underbody system neatness. Audley's car is finished underneath as good as on top. The paint judges were checking door gaps and finish inside sills and all that. Good job I thought. At least you scored better than last year!
Cheers
Brett
