Worth every penny! It's probably not for everyone as the ride is a bit on the harsh side. Actually harsher than my Miata (but that's probably due to the Honda feeling stiffer overall). However, the payoff comes in the first corner you take! The engine is amazing. The sound is unbelievable. The best gearbox I've ever driven. All in all I'm very happy with it, but might've liked a variable suspension setup to soften the ride a bit in town. (I'm getting old 8)
Engine. Suspension setup. 50/50 balance.
Paddle shifters, better head unit and better speakers. Ability to close the top while driving (speed limited, like in Europe).
