Old new guy here. Bought my first Porsche in 1967 when I was a 24 year old kid looking for a used sports car. Still have it: 1963 Cabriolet 356BT6 Super. Bought a 2008 Cayenne S about 8 years ago. Its been fairly reliable. No running problems, however, I am getting tired of air bag lights and check engine lights that neither the dealership nor independent garage knows anything about. It gets expensive when they just throw parts at it. (Airbags, seat bases, Vacuum pumps plugs, coils etc) Somebody, somewhere, has always experienced an issue before me and I find joining a forum to be beneficial.
