🚗💥 The 1955 Mercedes-Benz 300 SLR Uhlenhaut Coupé is a wild piece of automotive history! Selling for ~$142-143 million in 2022 at the Mercedes-Benz Museum, it's officially the most expensive car ever sold.

- *Why so pricey?* It was a road-legal prototype with Formula 1-level tech, designed by chief engineer Rudolf Uhlenhaut. Top speed ~180 mph. One of only two made.

- *Compared to modern ultra-luxury cars*: Rolls-Royce Droptail (~$30-32 million) and Boat Tail (~$28 million) are super pricey and bespoke, but way below the Uhlenhaut Coupé's record.
