If you can point me out one single post where I, or anyone else, has said that a standard Jag or Porker is a supercar, I'll buy you a 10kg tub of Jelly Babies.
Also, if you bother to read my posts on this thread, or anywhere else, you'll see I talk the 350Z up as a bloody good car and that I'd take one over the many rivals. But of course, that would take time and effort, and it's far easier to take the lazy route and simply state that anyone who no longer owns a Zed but still sticks around because this is a great place to be must hate all Zeds and always puts them down.
But hey, whatever floats your boat.
