friend of mine has a gti and claims it's faster stock than the r32....dunno if I believe him.
I test drove an R32 a couple of days ago and it sounded great, and the power delivery was smoother and more immediate (as you would expect from a N/A car). However, it'll be less readily tunable given how easy it is to tune turbo charged cars respectively...
To hinder things further, the 4WD is always nice to have
