A car does Frankfurt to Liège in roughly 3h 15 over 310 km. There is no direct motorway between the two, so the road covers 310 km across 228 km of map — 82 km of that is the detour. The difference from every other way of making the trip is that it starts at your address and ends at theirs.
The fare is fixed when you book, so a closed lane or a slow stretch costs you time and not money — there is no meter and no waiting charge. Pickup is any address in Frankfurt: a home, a hotel, an office, a venue. Drop-off is the exact address in Liège, not the nearest station to it. The route crosses from Hessen into Wallonien; the price covers the whole of it including tolls. The same fixed-price arrangement covers Frankfurt to Monschau, a separate route with its own measured distance.
An executive saloon on a 3h 15 run is a quiet place to work: the same car the whole way, no changes, no platform, and a driver who takes the route. Longer bookings are usually made a day or more ahead, and the return leg can be fixed at the same time and the same price. Arriving by air instead?
