The drive is 216 km against 171 km as the crow flies, which is the ordinary shape of a German motorway journey. That is 2h 22 in a car that waits for you rather than the other way round, at a fare quoted in full at booking.
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 Mainz: a home, a hotel, an office, a venue. Drop-off is the exact address in Düsseldorf, not the nearest station to it. The route crosses from Rheinland-Pfalz into Nordrhein-Westfalen; the price covers the whole of it including tolls.
An executive saloon on a 2h 22 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?
