If the million car mag reviews praising how fun the BRZ/FR-S is to drive don't convey the appeal, then you really need to go drive one to see if it floats your boat.
It is not crazy fast, but it is a ton of fun to wind out with a very willing motor. There's a lot to be said for a proper road car, which is a point that I think it lost on a lot of people. The requirements for fun on the street are very different from those to be fast on a racetrack. Fast is most certainly one type of fun, which is why I own a 260, but a balanced car with a nice stiff chassis, low center of gravity, good power delivery, great gearbox, and communicative steering that lets you "drive" the car, versus simply mashing a pedal, is incredibly fun in a daily driving situation.
I've said before that after years with Elises, Evos, and STIs the BRZ reminded me of the simple joy of a good second gear corner. It's an instant classic to me.
