6. Ford Probe
The Ford Probe, introduced in 1988, was a front-wheel-drive sports coupe developed through a collaboration with Mazda, sharing its platform with the Mazda MX-6. (en.wikipedia.org) Initially intended to replace the Mustang, its sleek design and Mazda engineering offered a compelling package. However, Mustang enthusiasts rejected the Probe, leading to declining sales and its eventual discontinuation in 1997. Despite its potential, the Probe’s unique blend of Mazda engineering never received a true successor. (autoevolution.com)
