On Saturday I will have owned the BRZ for exactly 4 months, so I thought I would put my thoughts about it down here, both good and bad.
The good: Has to be the way it drives. You always want to take the long way home. Steering feel is near old style Porsche level, and that's a compliment. Its also economical to own. I average about 30mpg for mixed driving, and in fact, my average since I've bought it (it now has 5,027.6 miles) is 30.8. There have been zero repairs or trips to the dealer, and it still looks and smells like new in all regards. People like it and point to it almost everyday, and no one cuts you off and thinks you are a tool in the way they did with the 370, or the Cooper S for that matter. And with the low speeds, you can have a great time without the fear of going to jail.
Where the 370 was all seriousness, the BRZ is simply fun all the time. That's the best compliment I can give, it's just a fun, rewarding car to drive.
The bad: Has to be the engine. I simply do not care for it. It feels out of place in the car. The old 2.2 boxer in my previous '97 Impreza was a great motor. This one misses the mark, and I can't put my finger on why specifically that is. I think it is that I keep wanting it to feel more like a 4AGE or F20C. It needs more torque, but you never get that satisfying at the rev limit feel the F20C delivers. Its just buzzy and the power never appears.
Seats. Not really bad, but bad for my back. I had the seat modified and it has helped, but there are still some issues I need to address. This isn't a fault of the car but my older age.
Tires: Not bad for driving back and forth to work, but as many here already know, they are not a performance tire and on ramps tax them greatly. They squeal at the slightest change of direction too.
Shocks: Very stiff compression, crap on rebound. Its easy to overdrive them. These are probably my first change to the car. Of course my friends say I'm overly shock sensitive, but if you get them changing directions quickly, the shocks simply are overwhelmed.
Summary: Its a great car for the money. Certainly not perfect, but there aren't many new cars you can pick up in this price range that will drive as well. Most of its problems the aftermarket can fix. The engine, well, its almost a spoiler for the whole car. The big question is would I buy it again. Don't know at this point. In many ways I like the 370 far better. It was certainly nicer, easy to cruise long distances, and the BRZ isn't in the same ball park in terms of speed. But the BRZ is great fun as a low speed car. And of course it was $15k cheaper, which makes it a bargain.
