I think it's probably the only circuit other than say maybe Silverstone that will really favour the Leon's speed.
I have faith in Alan Gow that he doesn't jump to conclusions based on one good race weekend. The Vauxhalls have had the measure of the Leon most of the year and this is the first round where SEAT have truly been dominant.
If it continues to be dominant at Oulton Park, then i think questions maybe asked.. But I doubt they'll have it as easy at Oulton.
