I owned a Mk3 GTI for a couple of year and now have a mk2 16v. I think the mk2 is a much sportier drive and it looks so much more iconic than a mk3.
I bought a late mk2 which has power steering and most of the stuff my mk3 had. As the mk2 is an older car just be prepared to look after it, if you can handle the odd problem then what are you waiting for go and get one!
I love my mk2 and im glad I switched.
