My friend is asking me what he should look for in a 2008 Cayenne GTS with 61.000 Kms (38k miles). I told him the cayenne is very reliable but do they have a big service or major parts that will need replacement soon ( 50k miles ? 75 k miles? ) The guy wants 45K Euros.
the major service is every 4 years/40k miles. while not a direct comparison, it was ~$1k for that service on my 997. here's a link to a PDF detailing the services: http://www.porsche.com/filestore.aspx/default.pdf?pool=uk&type=download&id=porscheservice-cayenne-infobrochure-pdf&lang=none&filetype=default
