The bargains are out there if you're patient enough, i picked up mine for 3.3 with all the engine/suspension mods done, and 2 sets of wheels. No idea of the power but i've had an indicated 150mph from it, and it outdrags my remapped 1.8T mk4 which does 0-60 in 6.5 secs.
Going rate lately seems to be 4.5 - 6k for tidy examples, but if you're lucky you'll find someone selling what they think is just a G reg golf with jetta headlights, a bodykit, and a whooshy thing under the bonnet
