First Generation Porsche Cayenne as a used purchase- Can you afford to maintain it?

I was recently asked by a reader on the possible maintenance costs of running a first generation Porsche Cayenne (2003-2010) in Malaysia. The first thing that crossed my mind was money. Lots of money required to do so. The infamous saying that if you have to ask means you cannot afford it comes to mind. But then again, this is Malaysia, there could be a hope in hell with all the Cayennes you see running around the country. Anyway, I asked a few people, poked around a bit and found out a bit more about the SUV that basically saved Porsche from an early death. I have informed the chap and I believe that I should share some of the findings with you folks out there.
