A fine riding mechanic, most notably to Ralph de Palma, Alley was a decent driver in his own right, who initially worked as a test driver before going racing. Later worked as a car repair man., running his own garage for many years. He raced from 1913 onwards after starting his working life as an automobile mechanic and was a regular racer until America entered World War 1, in which Alley served. Thereafter, although Alley carried on until 1925, it was virtually solely confined to the Indianapolis 500.
