My first car, a Rambler, was named "Ernie" by my friends and it just stuck. The license plate ended -ERN . The name seemed to just fit the car... and no car with the same tags on it have held the name since.
The Boxster has a vanity plate and some people refer to it by the name on the plate, but not me. It is always just "the Boxster" or "the fun car".
