1958 Lincoln Continental
Exaggeratedly long, the 1958 Lincoln Continental resembled a boat more than it resembled a car. Add to this exaggeration an over-styled massive front bumper, slanted and stacked headlights, and an overhanging roof, and you have yourself a design failure. Yet to be fair, Lincoln has come a far way in the design market; the 2018 Lincoln Continental is quite snazzy.
