Based on Jaguar's legendary D-Type race car, the E-Type took the automotive world by storm upon its introduction in 1961. With its classic lines, independent suspension, powerful inline-six motor, and disc brakes, the E-Type raised the bar for what was possible in a production vehicle. All this performance meant it had to be raced, and this 1963 Briggs Cunningham Lightweight E-Type proves the pedigree. Stripped of everything not necessary for the track, this E-Type thundered for 24 hours at Le Mans and the 500 miles of Road America and Bridgehampton, earning the title of "GTO killer" for going head-to-head with Enzo Ferrari's vaunted 250 GTO on the track.
In 1966, Ford partnered with the Hertz rental car company to give travelers something a little more exciting than the usual American sedan — the Shelby GT350-H Fastback. But it wasn't people on vacations and business trips that rented them. Affectionately known as the "Rent-a-Racer," many of these GT350s ended up on the track at race weekends, coming back on Monday with bald tires and evidence of roll cages being welded in. With around 1,000 produced, the car is rare, even by Shelby Mustang standards, but this particular example is even more scarce with its Ivy Green paint instead of the typical black. It crosses the auction block at Barret-Jackson June 21-24.
