Ooooooh, just thought of a few more:
1. 1973 Pontiac Grand Am(looks like a giant electric shaver)
2. 1972 Buick Riviera(love child of a Electra 225 and a 1964 Corvette)
3. 1983 Mercury Cougar(what's up with those Gremlin-esque quarter windows?)
4. 1987 Mercury Cougar(how could you restyle a car to look worse ?)
5. New BMW Z3 Coupe(pug-ugly, but I still want one)

Cars ruined by US mandated bumper laws in 1974:
1. MGB(can you say "rubber baby buggy bumpers" real fast?)
2. Chevy Camaro(Huge cow-catcher bumpers ready for battle)

More nominees for lameness:
1. 1979 Pinto sport wagon(you know, the one with the mini-custom van styling:port holes, rear window louvers, wild paint schemes- from the factory! )
2. 1978 Mustang II Cobra II(with billboard side stripes)
3. 1980 Corvette(Not ugly, but Oh, how the mighty have fallen! Would you believe these performance numbers-0 to 60 in 7.6 secs, quarter mile in 15.9 secs, top speed 123 mph, and 14 mpg, all with a 190 horsepower 350! The ultimate white-shoes-and-belt car.)
