15: Oldsmobile Siloulette
An Oldsmobile van was always a quirky concept, but GM was one of the first carmakers to try and market a “luxury”-minded minivan. Unfortunately, the dustbuster styling of the Silhouette didn’t quite equate with American luxury, and buyers weren’t convinced. Again, the higher-ups at GM were trying too hard to market something that most people didn’t want (via Auto Trader).

The Silhouette will undoubtedly go down as one of the biggest failures to come out from General Motors during this period. The odd-ball styling and the high price tag were not enough to convince consumers that they need to buy one of these luxury minivans.
