1915 Hispano-Suiza
This car from his collection was featured in the first episode of the seventh season of My Classic Car. The 1915 Hispano-Suiza is equipped with an aircraft engine that was taken directly from a First World War fighter plane. Whoa! There were only 49,800 such engines made. Eventually, a Soviet Union aero-engine derivative was released and called the Klimov V12. The Hispano-Suiza 8 and the Klimov V12 were both used during the Second World War. At the time, the military forces of the Soviet Union borrowed a lot of ideas from the West. Anyway, the Hispano-Suiza used to be on the market for $1,964. Nowadays, you will need to pay $1.7 million if you want to bring one of them home.
1931 Bentley 8-Liter
Jay Leno drove around Los Angeles Kelly Rowland in his 1931 Bentley 8-Liter as well! This is another impressive car from Bentley in his collection. W.O. Bentley himself used it as his daily driver, which explains why it now has a value of $8 million even though its original value was only $2,271. This also happens to be the last car that he ever designed for the automaker. Weighing 5,000 lbs, the Bentley 8-Liter comes with a SOHC 8-Liter I6 engine under the hood. The top speed is 101.12 mph, which was super impressive in those days. This model was also the largest car that Bentley produced.
