Munich to Marrakech and back in 22 days. I drove 8.500 km , slept in the car and enjoyed a great time.
Despite having started with just shy of 270.000 km on the clock, the BMW never caused any trouble. The only time I came close to breaking down was when I tried to save money by refueling in Andorra instead of France. Found a petrol station with 14 km of indicated range left. And when the turbo started whisteling, it was just due to thin air, 2500 m up in the Atlas.
