Morning Hugh - I agree with your comments, the STi is a bit more hardcore, the WRX is more practical for an every day car and it is still quick but looks more understated than the STi (some people prefer this others not).
I have done 2 track days in my Impreza, one at Cadwell Park and the other at Oulton Park. Awesome fun
I am not a racing driver by any stretch of the imagination, just went fast for me.....got overtaken by a stack of Caterhams. Had a couple of blasts against Lotus Elise's, blew them away on the straight but they were crawling all over me through the bends. Although the scoob handles great it's surprising how soft they feel when you put them on a track!
I am planning to take the Fiesta ST on a track as I reckon it will still be quick enough to have some fun with and should be good through the bends - What do you think?
Sorry for hijacking this thread by the way!!
