4. Reliant Robin

Mostly unknown to the automotive public outside the United Kingdom, Reliant has been producing cars since the 1930s and three-wheel vehicles since the early `50s. In 1973, Reliant introduced the Robin, just in time of oil crisis which greatly helped the sales. With its 850cc engine and around 50 hp, Reliant Robin weighed just less than 500 kilos which made it surprisingly agile and fuel-efficient.

However, the three-wheel configuration was tricky in tight turns and Robins was known to flip over if the driver entered the curve too fast. Although slow, Robins wasn’t safe at all. Despite all that, many collectors include this little plastic three-wheeler in their collection.
