DK is right in that from factory the RS3 has serious flaws in tyres and roll but replacing both has transformed the car. Is it as dynamic as the '4; no. Is it as tuneful; as much as the 5 pot is nice it is not a V8 but the plus points are that for a fraction of the cost of the money I invested in modifying the RS4 the RS3 is quicker, bigger inside, more fuel efficient, nearly as good dynamically now (for what my ability can use) and it doesn't drink a litre of oil every couple of k miles but still has the exclusivity of the '4 the Golf will never give. I still like my $WD assurance to which only the Golf R (?) would give. As for s-tronic, being a staunch manual man for the last 22 years I'd happily say I wouldn't go back and the s-tronic is so flexible to everyday driving needs, D mode for tootling in rush hour stop start or cruising, s mode if you want to show someone a clean pair of heals and manual if you want to be part of it or twisty road work. And of course Lauch Control......

If I were in the market now and had to choose a used RS3 or a MkVI GTi it would be a different proposition from that I found myself in a year ago and I may choose neither but if they were the only two cars I had to choose from I'd still pick RS3 for its tuning potential. It's not perfect and it may not be worth twice as much used but each to their own.
