the Skoda VRS is an awesome car, personally i'd never swap it for a Fiesta ST.
also, i would never have a daily driver and take it on the track too, you are better off keeping the Skoda and buy a cheap track toy whereby you can fiddle around with.
incidentally the clio 172 & 182's make awesome track cars and are reliable.
if your budget doesnt strech that far, buy a pug 205 gti and use it as a track car (i'd love a 205 fitted with a gti-6 engine). plenty of track cars for sale on pistonheads/ ebay
