mental_floss has a neat article on 5 cars that became metaphors, whether deserved or not. Like this one:
4. Dolorean = Overhyped
The DeLorean has such a wild story that it became more than one metaphor. Built from 1981 to 1983, it was the dream project of John Z. DeLorean. A Detroit native and engineer and executive at GM, DeLorean founded the DeLorean Motor Company with the help of high-profile investors and huge financial incentives to build his factory in Northern Ireland. Only 3,000 of the strange-looking and expensive car sold the first year, nowhere near DeLorean’s projections. Trying to pull the company out of British goverenment receivership, DeLorean became involved in a cocaine-smuggling scheme and was arrested in 1982. He was eventually found not guilty due to entrapment, but the damage to his reputation, and to his car, was already done.
