THE Volkswagen Golf GTi has grown to become a more spacious, luxurious performance hatch - a concept that appals GTi purists even though the car retains the virtues of being fun to drive as well as a practical load-carrier. With a full Recaro interior, it is superbly comfortable and has enough luxury equipment to appeal to the most hedonistic of buyers, while a low-pressure turbo engine provides enough power for swift, satisfying performance. It is just that the new car fits better with Armani suits than cargo pants and Mambo T-shirts.
