No. I love my car and think it's super cute and I have always developed a close personal relationship with my vehicle, but I have never named them. I always give names to the letters on the number plate to help me remember it though.
If you use the 'Phonetic Alphabet', it's very easy to remember! eg 123-XYZ, would be 123-X-ray-Yankee-Zulu.
Once you start using it, & many Assist Services do......Police, Ambo's, SES, Fireries, as well as ATC, Airlines, & Shipping.
It's International, so words don't get confused. Same goes for '24 Hour Clock', once used, not forgotten! Cheers, ladies!
