After reading/viewing everything I could find published about the '17 performance pkg BRZs and getting a huge amount of help & direction from a post I made here about 6 weeks ago, I picked up an Ice Silver PP BRZ yesterday!
Drove from KY to Charlotte NC to get it. I'd worked out a deal I cd live with via email and a couple phone calls with Williams Subaru, took a deep breath and made the trip. All the numbers were the same once I got there and I was out and driving in just over 2 hrs, maybe a personal best for me at a dealership.
Put about 150 miles on it yesterday with a big, stupid grin on my face. Even topping out at around 4K rpm, the car is just a pleasure to drive. Such great steering, gearbox, brakes, interior, seats, driving position. The big surprise was how quiet it is on the road. Not that the STI was a bad driving experience at all, but I'm bonding with this thing hard!
My calculation was that I'd be trading exceptional power and an adequate chassis for an exceptional chassis with adequate power. So far, it feels like that's what I've done

Thanks to everyone that chimed in on my original posts, you're a good group!
