Some good stuff in this thread. I almost picked up a 2011 Mustang V6 when they first came out. Glad I did not and waited for the BRZ. OP just helped me realize something. Unlike my previous vehicle, 2010 Cobalt SS turbocharged with GMS1, this car can be driven hard, but still in legal limits. My Cobalt, even though it was a little 2.0L turbo, it was very easy to get in trouble with that car.
I enjoy driving my car hard, and the best thing about the BRZ/FR-S, is that you can, and still keep it legal (most of the time). If I ever were to trade this car in though, the 2015 WRX is looking very tempting. However, I hope that does not happen because I really do enjoy this car, even if it remains stock for the rest of its life. I think the power in this car is just fine
