As a long-time Audi owner, including an Audi turbo car, I will say this:
I love my Audis. They do much well, and little poorly. They fit me and my driving style well. I daily drive an older Audi, and wouldn't trade it for anything. But the Porsche is a world apart from all those cars. The simplicity and the experience is completely head and shoulders above any Audi I've ever been in. And this includes a 1995 RS2. That RS2 was stupid-fast, and every bit an Audi.
But it's no Porsche.
I really like the UrQ, too. In Ocean Blue, please.
And an RS2 in Nogaro. Might as well have both.
But neither car will ever replace my Porsche. It (or they) would only be in addition to.
