The XK140 represents the sweet spot of the range, as it offered more power and refinement, but retained the elegant lines of its predecessor. This XK140 looks like it's been beautifully restored, and it's especially desirable thanks to an upgraded 5-speed manual transmission and the MC Package, which added dual carburetors and other benefits. Power comes from a 3.4-liter straight-6, rated at about 210 horsepower and 213 lb-ft of torque. Output is sent to the rear wheels via a 5-speed manual transmission.
