The rear brakes had to be replaced twice and the alternator broke after 140000 km.
A very reasonable car, not really fast but sporty enough for everyday use. Very reliable.
I had a Polo GT for 5 years and it was as stated good fun. Quick enough but not stupid.
I am old enough to have cheaper insurance, but the Polo GT provides a good entry for younger HotHatch drivers.
Mine was in Alpine White '91 with a set of 14" Oz alloys, 185/55 Pirelli's, a Jetex Oval exhaust system and a Pioneer CD system.
Not too costly for a nice looking car. I replaced it at 140,000 miles and had no major problems with it.
I run the Polo GT Owners Club - it's a great little car that is cheap enough for the younger drivers to own, whilst being more than capable of embarrassing cars costing considerably more to buy...
