The Jaguar XK120 is a classic whose lines and performance have stood the test of time — but that doesn't mean it can't be improved. This 1951 XK120 has had a suite of modifications to make it even better than the original while still retaining the gorgeous lines and soul of what made it one of the best sports cars of its day. The original steel body has been replaced with lighter alloy panels, and the 3.8 liter inline six has been modified to make 280 horsepower. The electronics have been updated to modern standards and disc brakes have been fitted at all four wheels. The matte gunmetal grey exterior contrasts beautifully with a fresh brown leather interior, and details like a leather bonnet strap and punched aluminum passenger footrest give it a decidedly racing vibe. This is a classic that can be driven without fear in modern traffic.
