Unlike the previous reviewers, I wasn't looking for a SUV, as such, I did not really do any due diligence on the Audi Q6 or BMW X5; it was really either a luxury saloon upgrade for my 520i or the Cayenne. In the end, we decided on the Cayenne because this is the only Porsche where the whole family can actually experience together.
I love the handling and steering. The Bose sound system is very rich. And then there is the "Sports" button.
Well, I think the standard interior is not as good as other modern European cars. I chose the nice Havana/Sand interior but am currently paranoid about how to maintain it.
