2010 Chevy Aveo
Clearly, Chevrolet was attempting to break free of the jellybean-shaped subcompact cars. However, while the exterior design is less than appealing, the interior is worse as it was cheaply made and had a serious lack of soundproofing.
1992 Subaru SVX
Subaru is known to have practical and dependable cars that can do just about anything. The SVX is not one of them, unfortunately. Aside from the useless 4-speed transmission, its exterior looked like it was created by accident. The Italian-designed model had split windows-within-windows for some unknown reason which were difficult to use. To top it off, the car cost almost $10,000 more than other Subaru models.
