Yo Adolf. I've got enough Porsche blood in me to feel that my comment may hold some weight here. My dad has a room dedicated to 911s, ask him
anything. I've got a friend that works in Weissach. I've personally put a '77 Carrera 30m down a cliff (video is somewhere).
Be aware that the Cayenne is actually a VW Toureg is actually an Audi Q7!
en.wikipedia.org/wiki/Volkswagen_TouaregBut seriously splash out on a car for your mid-life crisis. DO IT! Pick the right one and it won't devalue, may even go up. You could put your money in the stock market and watch it trickle away, or enjoy the time you have on this earth.
Perhaps get an old 911 for the near psychic steering response, and the just-when-you-least-expect-it oversteer. ~$40k. If you master it nothing in a car is as satisfying as throttle steering a 911. Nothing. (obviously I didn't master it). Ask Richard Hammond.
911s are fully galvanised since...the 70's?. Can put salty boards on the roof.
If you can't decide
just get them all, one-at-a-time! You only risk the cost of registration each time.

I keep finding myself looking at Maseratis.
