Reviews I'm seeing are that the GR is a blast to drive, but most won't want to use it as an only car due to the more hardcore nature of the car. It's more of a toy.
To me, that defeats the purpose of a hatchback, and is why I love my mildly modded GTI so much. I slogged through traffic this morning, comfortable as could be, I can put seats down and make a run to get mulch, I can pick up the kid and friends from school and drop at soccer practice, and then track it this weekend, and it does all of them pretty well. Only downside to the GTI/R for me is the cooling capacity and blowing smoke under braking, which can be fixed with a variety of PCV/CC solution and an oil cooler.
