1 Of 50 Worst Cars Of All TimeThe 1961 Jaguar E-Type was heavenly, a dead-sexy, 150-mph supercar, a stiletto heel to the heart of any car-loving man. By 1974, it had morphed into this, this thing. In order to compensate for power-sapping emissions controls required in the U.S., the car's primary export market, Jaguar discontinued the reliable 4.2-liter six for an anchor-heavy 5.3-liter V12, which was a total bitch to try to keep in tune and made the car nose-heavy besides. Jaguar also discontinued the elegant fixed-head coupe and offered the car only as a long wheelbase 2+2 or convertible. Imagine taking one of the world's most beautiful cars and sticking it in a taffy puller. Not finished ruining the lines, Jag plumped up the fenders, spoiling the smooth, aero-sleek contours of the original. The piece de resistance, Jag affixed hideous rubber bumpers — Dagmars, really — in a lame attempt to meet 5-mph bumper standards. To which car enthusiasts can only say, "You ba@#*&ds!"
