In the 1950s to 1960s, three wheel cars were very popular in Great Britain. For drivers with a motorcycle license, these cars did not require a separate car license. Berkeley redesigned the rear of their 328 model to fit a single rear wheel. The result was a three wheel sports car which filled a gap in the market left open when Morgan stopped 3-wheel production. You will notice that it is hard to tell that the T-60 is a three wheel car unless you look at it from the rear. The T-60 was Berkeley’s most successful model. Most were open top cars, although a few cars were made with hard tops. Berkeley produced 1,780 of these models.
