Kestrel Take

The luxury SUV for drivers — the Cayenne handles like nothing its size should, with a gorgeous cabin and genuine Porsche engineering. That comes with Porsche running costs: the (supercharged/turbo) engines, air suspension, and service are expensive. A documented Cayenne with full history is a superb, capable luxury SUV; a cheap undocumented one will drain your wallet. Buy on records, verify the engine and air suspension, and keep a serious repair fund.
