Well played sir! Lovely cars and environment to match - I'd be interested to hear about your comments on which car is useful when. I've only test driven a GTR before I got my DB9 and whilst it was an absolute weapon, I wanted more of a GT cruiser with the ability to cross Europe with minimal fuss and maximum fun.
This pairing seems similar in that regard - both are, in my limited experience, 'track focused' cars (though I'm sure they're both fine on the roads too - particularly the 12C) - which would you pick for a 500 mile journey up the coast? My thoughts are that I would be tempted to choose between them (for a 'track focused' road car) then picking up an epic GT such as a new DB9 or Fezza California to pair it with.
