My parents didn't have a car, but did have scooters - the first two (I was 7 and still remember the registrations) were Millicent and Phoebe (no idea why). Then my dad decided he wanted a more powerful one, a German top of the range Heinkel model (no, I didn't know they'd moved into the 2-wheek sector either), which became Hank. My mum-s first 3-wheeler was a Reliant Robin, which didn't have a name, but then she got a DAF which she wasn't very good at - saw it hopping down the road, so clearly known from then on as Kanga. None of ours ever had names. Funny - don't know why some have names and personalities, others not.
