32: Jaguar S-Type
Sharing almost all its components with the X-Type, the Jaguar S-Type was meant to be a more sedate model in the lineup. The smooth lines and beautifully sculpted interior and exterior were far ahead of their time, and the S-Type was initially a strong selling model for the brand (via Car & Driver).
The Jaguar S-Type was one of the least reliable models ever with a Jaguar badge. For years, the S-Type would soldier on in the line, but consumer tastes for luxury cars were shifting. The Jaguar brand was left in the dust by rivals, which became more luxurious and offered better value.
