Used Cayenne from Porsche - Advice

[MPA]

Hi,
I would really appreciate some advice on a used Cayenne. I’ve got a budget of around 35k, and found a few from Porsche dealers.
Given my budget, id probably get a 11 plate to 14 plate.
The question is with regard to reliability. I plan to keep the car for 5 years and don’t want any huge problems.
Does anyone have any advice on general reliability, ie, were the older ones more reliable, or the same as the post facelift ones?

Thanks,
MPA
