Morris Minor
From Tardis Wiki, the free Doctor Who reference
Morris Minors were common cars in the 20th century. They were the most popular model in the UK for most of the 1950s, and were widely exported with some success, but were outsold by a wide margin by the (directly competing) Volkswagen Beetle worldwide.
In 1959, CIA agents, Hawk and Jerome Weismuller, used a Minor while in Wales. (DW: Delta and the Bannermen)
