Our take on the Porsche Cayenne
A 2023 Porsche Cayenne typically advertises at €73,000 and a 2018 one at €37,000, so it loses roughly 13% of its value a year at that age. Most for sale are petrols; diesels are rarer, at 17%. The 3.0 hybrid is the most common engine (81% of those with a known engine), and it usually lasts around 300k km.

Common Porsche Cayenne problems
Known weak spots to check before you buy, with typical Irish garage costs if the problem is there.
Timing belt history · €350–€700
Ask when the timing belt and water pump were last done (usually every 160,000 km or 5–6 years). No proof = budget for it.
Automatic gearbox health · €300–€2,500
Make sure the gear changes are smooth when warm, check for a gearbox warning light and ask if the gearbox oil was ever changed.
Engines and how long they last
| Engine | Usually lasts | Motor tax / year | For sale |
|---|---|---|---|
| 3.0 Hybrid | ~300k km | ~€200 | 51 |
| 3.0 Diesel | ~320k km | ~€600 | 12 |
"Usually lasts" is the mileage these engines commonly reach before major work; service history matters more than the number.
