Corvette C6 Or Porsche Cayman-S ?

At a point to buy another new or used toy. Im attracted towards two door coupes, preferably nice convertibles. Im starting to like the Cayman S, but I need something a little quicker. A base C6 Vetty comes equipped with over 430 Hp, but indeed it lacks the luxury and everybody knows Corvettes ride very low to the ground and the interiors look like hell. I dont like Lexus,Bmw, or Benz because those are way too common and boring looking on the road where im from. Porsche Cayman-S or Corvette C6? Which of the two are more reliable for everyday use with the least trips to the mechanic?? I dont drive hard, but I do drive fast on clear open highways every once in a while.
