I used to own an earlier version of the Robin, a Supervan III, while my brother had a Robin and hauled a camping trailer with it believe it or not.
They were a lot of fun especially as I only had a motorcycle licence and in the UK at that time you could drive a three-wheeler on a MC licence as they were classed as a tricycle the same as a motorbike and sidecar. You only had to pay the road tax for a MC too...much cheaper than taxing a car.
They were not as dangerous as some people would have you believe and had many advantages over a similar sized car.
