I owned my 2007 VW GTI for about 6 months and it's been in for repairs well over 2 months in total. The information center was defective. It took over a week to replace. Most serious problem could be related to the engine, transmission, turbo - don't yet know the source. The dealer can't identify the problem and VW tech support has been useless. Possibly related to heat, since it occurs most often when the temperature is high. As you step on the gas the car drops out of gear and will not respond. It feels like you are slamming on the brakes, according to my friend who was driving with me during one of these "seizures". This is a very serious safety issue. Car was bought back by the dealer.
It can really move, when it is running properly. A blast to drive.
Find the source of the "seizure" problem and fix it for good. If that were to happen, I would gladly buy another one!
