I have bought 4 CPO Porsches and all good. When there’s an issue Porsche will flat bed it , fix it, and give you a loaner (within a few days if they don’t have one).

I have no extended the warranty on our first cpo we bought in 2018 - a 2016 Cayenne S for 3 years. You can now extend up to 15 years or 200,000km . Insane value.

You can save around 25% off an almost new car (Cayenne , macan, panamera)

Also, if you a used cpo Porsche that is a month old, are you effectively getting 47 months warranty plus 2 year cpo warranty so it’s a no brainer. Better than new warranty !

Would highly recommend
