Can't believe my eyes your selling up so soon after buying the RS!
The Cayenne S V8 4.5 would not be my choice of car to swap into..
Performance is OK but the running cost is massive, they drink fuel like it is going out of fashion...worse then RS believe me
I would be temped by the Turbo..as they perform better get more options..drink less fuel(under normal driving)
BUT they both cost the earth to run...I have freinds who wanted them and they have now gone for Q7 or Range Sport...
Before someone asks yes I have driven them all for a long period and know what they are like and I know the running costs inside out on these things
If you still want one and need some help I can gladly help you out with all you Porsche needs!!
