Buying advice to Mini Countryman

Hi, I’m looking for a countryman for my wife. Since I didn’t drive a mini or have a big idea of this, I’m asking here for tips on what to take and what better not. At the online exchanges and the mini homepage I looked around a little and looked out the following criteria: – Mini Countryman Cooper (122hp petrol) – black metallic – seat heating – Xenon – PDC rear – sliding roof – from EZ 11/2014 (same facelift ???) – up to 20,000 km run – sports seats – 18″ Turbo Fan Rims optional: – Navi – leather seats or partial leather seats from private there is probably not at all in the equipment, mostly all former rental vehicles. What should you take, what better not? Where should you pay attention to the former rental vehicle at the mini?
