The GT4 is an amazing car. Much faster than an NSX in all regards. While I love the NSX and everything about it, its still a old car on a old platform. That being said, I'd still never sell mine and it never disappoints me. Its amazing it has stayed so competitive all these years against newer, faster, more exotic cars. The 355 is an amazing car too but feels fragile IMO. The Cayman is really something else, I can see myself having one on day. Possibly my first new car purchase ever.
