Just returned from my longest trip in my GTI, a week up in Scotland and well over a thousand miles covered. Car didn't miss a beat, and the ACC combined with comfort mode made the long motorway legs a breeze. It also returned just shy of 43 mpg at a constant 75 mph which is remarkable.
Then on the twisty roads up near the lochs I had a lot of fun with everything in sport mode. Such a joy to drive.
It just proves to me that the GTI is the perfect combination of performance, comfort and economy. Doing that journey in other performance cars I've driven in the past would have left me sore, deaf and skint.
Only downside is that the front of the car is now caked in dead bugs.
