9,500km on my 2011 Cayenne Turbo with no problems, my oil level has dropped 1 segment since the car came out of the workshop in July 2011 (Annual service + Software update) other than that, it's been a joy to drive this car.

Pros and Cons

+ Powerful engine options and sports-car performance
+ Attractive exterior design
+ Loads of standard safety features
+ New Cayenne S Hybrid is especially sporty for a hybrid

- Higher-level trims and hybrid are extremely pricey for the class
- Complicated instrument panel can be confusing
