The PORSCHE CAYENNE (2007-10) 5DR SUV 3.0 V6 TURBO DIESEL TIPTRONIC S AUTO6 is a large five-door luxury SUV, bringing Porsche performance and prestige to the family-car market. In the UK, it sits above mainstream choices such as the BMW X5, with a more distinctive badge and premium feel inside. It suits families needing passenger and luggage space, and drivers seeking comfortable motorway journeys with a more involving feel than an ordinary SUV. Diesel power can suit regular longer trips, but fuel, maintenance and repair costs warrant careful budgeting. mycarcheck.com records 2,376 look-ups across 482 distinct VINs, a useful sample. Checks show average mileage of 127,000 miles, annual use of 6,000 miles, nearly seven previous keepers, and a £7,100 average private-sale valuation. These are useful guides, not guarantees. Against rivals, the Cayenne stands out for Porsche character and diesel versatility, appealing to buyers prepared for older luxury SUV running costs.
