The drive is 472 km against 371 km as the crow flies, which is the ordinary shape of a German motorway journey. That is 4h 54 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 Stuttgart: a home, a hotel, an office, a venue. Drop-off is the exact address in Münster, not the nearest station to it. The route crosses from Baden-Württemberg into Nordrhein-Westfalen; the price covers the whole of it including tolls. The same fixed-price arrangement covers Stuttgart to Cologne, a separate route with its own measured distance.
An executive saloon on a 4h 54 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? Stuttgart Airport Transfers covers every destination we serve from the airport.
