That's what I like about it. I'd never call it generic though, generic compared to what? Another Porsche maybe, otherwise nothing else looks like it. You could argue that the Evira is "generic" super car in it's looks (McLaren or later model Ferrari's anyone?). But then of course, that's the whole point surely?
I have to admit I'm in the "Evira is too flashy" camp personally, I prefer to fly under the radar. Especially so as I live in London, and attracting attention in a car in London is likely to result in your not owng the car for very long. Caymans are practically 2 a penny here in London, so not many people take much notice of them*. That would suit me fine.
*Well unless it's a GT car obviously.
I have to say though as far as Caymans go, the 718 is my least favorite looks wise. I think the 981 got the balance about right between the overly curved "911" clone looks of the 987 and the over squared 718.
