25. 1974 Jaguar XK-E V12 Series III
The Jaguar E-Type was a fantastic car in the 60’s, with a sleek design and powerful engine. In 1974 it had become a shadow of its former self. Trying to meet the strict emissions standards of the U.S., Jaguar replaced the reliable 4.2 liter six-cylinder that was used in previous E-Types for a 5.3 liter V12. The oversized engine added a great deal of weight to the front end, making the sports car nose heavy. The engine was also difficult to keep tuned, as there were now double the valves. The exterior was unappealing, with a stretched out nose (needed to house that huge engine) and oversized fenders. The body lines were a mess and the bumpers were made of rubber, this was not Jaguar’s best outing and the sales reflected it.
