My neighbour has an old one, bought 2 years ago I think - one issue with a fuse that was a brief mystery but no major issues so far… He’s not doing many miles though.
He mentioned it shares a platform with an Audi and a VW - might mean parts aren’t quite at the Dammit levels of Porsche tax.
Spend £2.5k on a full deep service. Drive forever servicing properly every year enjoying the comfort, class and dignity you can pretend to have in one.
Why are Porsche cayennes so cheap. They seem to be getting cheaper and cheaper. £2.5k on eBay. Either it’s a dog or it’s a genuine bargain
