3. Jaguar XK 140
Even before the E-Type existed, Jaguar was building products that are just as – if not more – striking to look at today. The XK 140 is a perfect example. Built between 1954 and 1957, the car was an evolution on the XK 120 and offered more interior space, better brakes, rack-and-pinion steering and modern telescoping shock absorbers. A sophisticated car for its time, the XK 140 used a dual overhead cam 3.44-liter straight six that made between 190 and 220 hp.
