Yep, waited long enough and saved my pennies, spent $5M and got the purple / white one. My 6 y.o. daughter loves the color combination.
But one thing I notice with those FGT cars -- once you get good at driving them, you suck at the "regular" cars, and vice versa. It takes me time to warm up to the F1 car and drive it well -- but once I do that, I'm not used to driving other cars anymore and I have to relearn those. The timing and techniques are different enough to me that it throws me off, rhythm-wise.
Wahooweeps - I used to be like that aswell but after a while the transition between the FGT and "normal" cars does become a lot easier. In the end you will be able to go between the two and not have any issue getting used to normal cars.
