Let's be fair here - the vast majority of GTIs on the road are Golfs. Golf V GTIs outnumber 9N3 GTIs by at least 10 to 1, from the examples I see on the road.
On the rear hatch - there's a VW logo, and "GTI". Nowhere on either the Golf or the Polo are the words 'Polo' or 'Golf' displayed. Especially now that there's a 3 door Golf V GTI out, can you really blame a non-enthusiast who likes his or her cars for not picking their Polos from their Golfs?
I can bet that the same confusion also pervades the XR4 Fiesta and the XR5 Focus. And at a short glance, I'll be damned if I can tell an STi from a normal WRX...
