11. Lancia Beta
The Lancia Beta, introduced in 1972, was lauded for its advanced engineering, including transverse engines and high-tech chassis designs. However, the vehicle suffered from significant rustproofing and quality control issues, particularly in early models. These problems led to widespread corrosion, especially in the subframe areas, causing structural concerns. Despite its technical prowess, the Beta’s reputation was tarnished, affecting Lancia’s brand image for decades. (classicandsportscar.com)
