10: Lumina AVP
Along with the other ugly-looking minivan offerings from GM in the 1990s, the Lumina AVP was the Chevy offering. Having the same plastic body panels and dustbuster shape the Lumina AVP was not the looker many had hoped for (via The Sun-Sentinel). The Lumina AVP went through several trim styles during its relatively short lifecycle including a redesign in 1995.

Sadly, the dustbuster style of the Lumina and the GM vans, in general, was not enough to resonate with consumers. For the most part, consumers have generally forgotten the GM dustbuster vans of the 1990s due to their hideous styling.
