Compared to the high-horsepower Ferraris the RS60 was pitted against in its era, the diminutive Porsche looked like a loser on paper. Widely expected to up the power from its successful RSK predecessor, Porsche left the ultra-reliable, 160-horsepower flat-four unchanged. The transmission and suspension were also carried over, with the chassis being lengthened by four inches for more driver legroom and a more stable platform. The result was wins, with the RS60 picking up exactly where the RSK left off. This 1960 RS60 Spyder is considered one of the best of the 17 built, and one of just six delivered to the US. The car retains its original Wendler coachwork and engine and transmission. A meticulous restoration in the early 2000s brought the car back to its former glory, and was raced in vintage events up to the present day. This RS60 is expected to fetch over $5 million when it goes to auction at Gooding & Co.'s 2023 Pebble Beach event.
