Before I purchased my 2013 BRZ, I had a 2008 M3. I had absolutely no regrets selling the M and buying the BRZ. Sure, it had less than half the power at first, but the car was so much fun to drive. For a daily, you can ring it out and still have a blast. I also raced it for 3 years before I received overseas orders. I did not want to sell that car. I've owned a C6 Corvette, 2 MKIV Supras (one that put down over 700hp), 5 WRX's (3 being STIs), and a variety of other cars and I didn't like any of them as much as I liked the BRZ.
Some people will have a completely different opinion, and that's fine. Everyone is different. But for me, for a daily, the BRZ was perfect. If I wasn't in Colorado for the time being, I'd have one right now. I do miss the instant torque anywhere in the rev range that the Corvette had, but the BRZ was plenty adequate.
I will say that I didn't truly begin to love the BRZ until I replaced the exhaust, headers and all, and got a tune. That eliminated the terrible torque dip that seems to plague these cars. That dip in torque is at the worst spot in the range, but it's easily eliminated. Plus, who doesn't like the boxer rumble?
