I'm thinking of replacing my X5 with a Cayenne, and budget I have for this car is only for the used ones.
I'm looking at 2015, 2016 with LCI tail lights.
I have very limited information on Porsche and I wanted to earn some insights when selecting a used P-car.

Is there any specific model year that is more reliable and any options that I must look for? Do I have to opt out for S model or is base good enough?
I'm planning to spend less than $55k (including tax) so selection is limited considering the model year I'm interested in. This is our secondary car and performance can be sacrificed as I would only drive it 5~10 miles daily for my commute. I've driven base model few times and while power wasn't so great, I was totally fine with how it drove, especially the handling.

How is the upkeep cost of p-car after the warranty?

Thanks in advance.
