Having had a few vehicles, this is the best SUV I have ever owned. And having had a Range Rover, I normally have no use for any vehicle out of warranty. The exception being the Cayenne.
The Swiss prefer this vehicle due to it's reliability; A choice of function over form. In our Winters, this is a safe, and reliable vehicle for the Alpenland. It will drive very well where other light vehicles, Yank tanks, and SUV's will get stuck in the snow or Farm soft spots. 100 KM is not much.
Skiing or Kayaking ? Perfect fit, rack mount ready, on and safe. Kiteboarding in Italia ? Everything for 4 fits into the boot, covered and unseen.
The S you are considering is a normally-aspirated (non-Turbo) V-8 engine, requiring regular tune-ups and oil changes to maintain it. Any mechanic can do this, and beyond a test drive I would have it examined. Where you will want to have it detail-examined, and in consideration of wear and tear after 100 KM, is in the following areas:
1. Drive shaft. Mine was replaced at 83 KM.
2. Oil seal: An inexpensive part, but an expensive repair. Look for leaks now.
3. Navigation: Others have had electrical problems; None experienced here.
4. Transmission: Given 100 KM, have that unbolted, dropped and examined well.
5. The usual: Brakes, shocks, wheels, tires, any damage or repairs, lights, +
It is a Porsche, and the design of this SUV started in 1998, so it is quite well thought out. As mentioned above, it is heavy and expensive. A very valid point is that there are blind-spots for the driver, at the left and right rear pillars. You train yourself to look twice + mirrors.
Hill climbing is amazing, and if the PSM feature is turned on as it should be, cornering, camber, and sway is smooth, with no roll or sliding, in ice or wet, as controlled automatically by the computer sensors. This is the same PSM feature in the 911.
Yes, I would, and I hope this is helpful.
