15: Jaguar S-Type
The S-Type was released after the Ford and Jaguar marriage was official. During this time, Ford was trying to introduce new and fresh products into the market. The problem is that the S-Type had a horrible reputation when it came to quality and most consumers just weren’t having it. The S-Type with the optional V8 engine spent more time in the shop than on the road (via Auto Trader).

The S-Type had a smooth exterior body and the interior was fairly well-appointed, but that wasn’t enough to sell cars. The S-Type would routinely get low marks with the automotive press and Ford finally discontinued the car after a lengthy run and years of failure.
