I visited a dealer a week ago to talk about ordering a Golf GTI. The dealership had a display GTI, Polo GTI and three GT TDI (2 of which had been cosmetically modified. The guy I spoke to owned the new Polo GTI and was adamant that, after having it chipped to 250bhp, it would outperform a Golf GTI. Got the impression he wanted me to buy the Polo (which does look suprisingly similar to the Golf in size etc.) but I quickly dragged him back to the Golf.
