10. Buick Riviera (8th Generation)
Introduced in 1995, the eighth-generation Buick Riviera marked a significant departure from its predecessors with a complete redesign. This model featured a more streamlined, teardrop-shaped design, drawing inspiration from vehicles like the Jaguar E-Type. Despite its sleek appearance, the Riviera faced challenges in the market. Its unique styling was polarizing, and the vehicle’s performance and features did not resonate with luxury consumers as intended. Sales declined steadily, leading to its discontinuation in 1999.
