I've had my GT for 3 months now and overall, I'm still very happy with my car - Definitely beats the Camry I drove for 7 years.
Pros:
-Engine Power
-Interior (especially the dash layout)
-Handling
-Fuel Economy
Cons:
The only con in which I hope is only related to the cold weather is dash noise. It's not at an annoying level yet but from time to time I hear rattling, etc. when going over minor bumps and imperfections on the road. Will be keep an eye (or should I say ear) on this
Most of my driving has been highway and I'm approaching the 8000km mark very soon. Highway fuel economy has been excellent with city fuel economy being okay.
When spring/summer rolls around, I'm planning to get tints (20% likely) and mudguards. Currently now sporting sexy winter tires on steel black rims . Can't wait to put the alloys back on by spring.
