New2 - its the same engine as a mk4 gti (and all the other VAG clan)
And for what its worth, Polo GTis seem to hold there value very well. I'm sure its a good car.
Doc is dead right about the journos. They are far too easily swayed by corporate hospitality and the usual PR spin - and of course it is wholly subjective, they have not particular qualifications to judge a car (Clarkson for instance - a fleet street type). Of course they are probably correct that Polo is not the most involving, but it has many other virtues. Not long ago a Citroen C4 was the best thing you could buyÂÂÂ

- now many journo's are suggesting an Alfa 159 is a much better proposition than an A4 or 3 series.. Hmmmm, they won't be when its worth peanuts and fallen to bits 4 years later

Take alot of the reports with a pinch of salt. DO however take it for a spin - if you don't drive the wheels off it 100% of the time it will probs seem great. If you love really full on driving, a Fiesta ST, CLio 182/197 would be a more 'involving' drive, but possibly not such a good 'ownership' propersition.
If hot hatches were bought entirely on road test reports and their ability to hoon down country lanes and entertain, Mk 3 and Mk4 Gtis would be as rare as rocking horse sh!t
