I only got to try it around town. Overall, I find it a great way to travel with a small group of friends. The vehicle accommodates eight passengers in the passenger cabin, plus the front seat accommodates a driver and front passenger seat is available for a bodyguard or an assistant.
I'm trying to imagine a highway journey. Vans have a high surface area for wind influence, and the Mercedes-Benz Viano van is very tall and quite skinny. So this may be a potential problem for long highway jaunts. If it's just a weekend getaway for two, taking a normal chauffeured sedan would probably be more comfortable. But a business trip with a long highway jaunt would definitely be better in a vehicle like this.
FBO? What airport is that?
In general, I find that these kinds of environments would allow me to get more work done than in the back of a chauffeured car. The club seating would allow for meetings to be conducted in face to face that is generally not possible in a normal sedan. The upright seating position and brightly lit interior is also heavily conducive to business.
