Agree with Hartsvuori & MJW's posts.
Having seen some coverage of the French Opel Adam Cup, those boys are showing no mercy, they seem to be driving at 10 tenths. I would have liked to see a similar Cup in the UK; I guess Vauxhall aren't interested in rallying. But, a single make series using current cars would be nice - but might not be popular here; as MJW so rightly said.

The most popular rally series in the UK are the Historics - for many British rally fans, the Escort IS rallying.
