2007 Pontiac Solstice (Worst)
Right towards the end of the Pontiac brand, GM would choose to release a roadster. The car had all the makings that made the Mazda Miata great. The problem was that it was decades too late. At this point, the Miata ruled the compact roadster market and no other car was going to intrude on that (via Classic Car Database).
The Solstice was buggy and cheap and there were better options on the market. The car just felt half finished, and that put a damper on the sales. Not to mention the 2008 Recession, which would also spell the end for the Pontiac brand. The GM restructuring effort just didn’t deem the Pontiac brand profitable. The Solstice has since become a rare vehicle that you don’t see often.
