The Cayenne is a really good 4x4 though, but it's not fun to drive, though if you're talking about would I take Dodge Viper/SRT-10 if I had the money? Then sorry the answer is no, it's not a drivers car, it's made for motorway driving and going in a straight line, no if I had the money I would buy a second hand F355 thank you very much.
I know of 1 person whose dream was to own a Viper, after reaching the point where he could do this, he tested a Viper GTS (Blue w/ White stripes), it completely killed his vision about the car as in his own words he said "it was a huge disappointment, the fantasy was much better than the reality". It's the same for people who long for a Countach as it really is a horrible car to drive, the car is meant to be used for GT driving, not tracking or about town, it will literally make you a body builder in a short time because of just how much work you need to drive the thing, not too mention you need a mechanic following behind you for when it brakes down!
