At number 5 is the Mercedes-Benz 540 K, a car built from 1935-1940 that was available as a two-seater cabriolet, four-seater coupe or a seven-seater limo. Throughout its reign on the road, it was considered one of the largest cars being driven.
Finally, we're here at number 1 with the Mercedes-Benz 300 SLR "Uhlenhaut-Coupe." Preserved in Mercedes' corporate museum in Sindelfingen is one of the two examples of the Uhlenhaut-Coupe that were ever created. Rudolf Uhlenhaut was the Uhlenhaut-Coupe's namesake, its designer, and the motorsport chief during the time of its production, and he used the SLR race car as a personal car. At the time of its production (mid-1950's), the Uhlenhaut-Coupe was considered the fastest car with a top speed of around 180 mph. The video notes that if the car was for sale not, which it will probably never be, it would more than likely be the most expensive car on the road today.
