I not sure when the first 3 wheeler appeared on our roads but most men of a certain age will know of the Morgan 3-wheeler(1932), which had all it's private parts on show at the front, primarily because it was powered by an air-cooled motorcycle engine as was the diminutive Bond Minicar, another 3 wheeler, powered by a Villiers 125 2-stroke air cooled engine, both of these cars are featured on Wikipedia, so what has the Bond got to do with this thread? The prototype was designed by Bond from premises in Berry lane, Longbridge, but actual production was at the Sharp's Commecials factory Preston, Lancs. 24,482 were built between 1949-66, when first conceived the 3-wheeler Bond took advantage of various lower taxes imposed on 3-wheelers at the time compared with 4-wheelers, but parity, when duties on 4-wheelers came down, meant the Bond no longer had a price advantage and was actually more expensive than a Mini.
