The first Cayenne, built from 2002 to 2010: the 955 to 2007, then the facelifted 957 with larger, more powerful engines. V6, V8 and twin-turbo V8 petrol engines were offered, and a V6 diesel arrived in 2009.
The versions

- 957 (2007 to 2010): 3.6 V6, 290PS; S 4.8 V8, 385PS; GTS 4.8 V8, 405PS; Turbo 4.8, 500PS; Turbo S, 550PS
- Diesel: 3.0 V6 TDI, 240PS (2009 to 2010)
- 6-speed Tiptronic S automatic; 6-speed manual on some V6 and GTS models
- All-wheel drive; steel springs or air suspension (standard on Turbo)
What to check on a first-generation Cayenne
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
V8 coolant pipes
What to look for: With the engine cool, look down the back of the engine and at the join between the engine and gearbox from underneath. Pink or white crusty residue, a coolant smell or a low tank are the signs. Ask whether the pipes have been replaced.
Why it matters: On the 955 V8s, plastic coolant pipes under the intake manifold crack with heat; Porsche's update uses aluminium pipes. Leaking coolant can also damage the starter motor beneath. On the 957 4.8 V8, a glued pipe at the back of the engine can let go suddenly. Paperwork for either repair is a good sign.
The propshaft centre bearing
What to look for: On the drive, pull away firmly from a standstill and listen for a clunk from under the middle of the car. Feel for vibration through the floor at steady speeds.
Why it matters: The rubber-mounted centre support bearing on the propshaft is a known failure on this generation. It's a straightforward repair, and upgraded carriers are available.
Bore scoring signs on the 4.5 V8
What to look for: Before starting, wipe inside each tailpipe with a white cloth; heavy black oily soot is a warning. From cold, listen for a knock or tapping that doesn't settle. Ask about oil consumption.
Why it matters: Cylinder bore scoring affects a minority of the 4.5 V8s in the 955 S and Turbo. Oil use, misfires and a knock at idle are the signs. A borescope inspection gives a clear answer.
