We picked up the car at the Volvo delivery center in Goteberg, Sweden and drove to Oslo, Lillehammer, over the mountains to Balestrand, back through Sweden, Karlstad, Stockholm, Kalmar. Climbing the mountains was no effort for the V8 and was unaffected by the altitude. We drove 1700 miles in ten days. The only challenge was parking in an Oslo underground garage meant for the dimunitive European vehicles. Mileage for trip was 23.8 mpg which is excellent considering the mountain and in city driving. But minimum octane in Norway/Sweden was 95. I've been a Honda/Acura owner for 30 years. Owned an MDX and test drove a new MDX recently. The Volvo XC90 is the ultimate.
I can't imagine a car being more comfortable than the XC90. I wish they made couches.
Price is steep but then so is the BMW X5 and MDX. I would add keyless entry.
