If your looking for fun go with the Nissan GT-R. Better in every measurable way then most 911 models and priced closer to the caymen. More practical, safer, closer to your Hondas in reliability, and a less common sight a clear winner. If your looking for "the look" and a much nicer badge, cleaner look, more prestige Porsche is the answer. Boxster is too much a girls car, Caymen or "coxster" as Jermey Clarkson calls it is "underengineered, a great car but you get the feeling it could have been better if they weren't worried about pushing into 911 territory," the 911 well it's a constantly improving icon. For transparency I have never driven any of these cars but they are a passion and I have read many reviews, and enjoy rehashing the knowledge as my own. The Porsche/GTR choice has been something the I have been imagining mulling over since the GT-R was reintroduced, I doubt I am of much help but I cannot resist talking cars at every opportunity.
