All my cars get names, usually based on a trait of theirs.
My first car was a great little Corvair Monza convertible and we were both in our early 20's. People used to yell "hey baby" at us when I run around with her top down, so she was named Baby.
My next car was a coppery color Phoenix hatchback and I named her Cinnamon. Then my Mom teased me and said " why don't you just call her Cin" ? So I did. She became the Sin-mobile.

It was mostly a joke cause I was behaving pretty well at the time.
My hubby had a white Dodge Dart with spots of a few colors of primer on it. He never got around to repainting the whole car and it looked awful. The blue, rust color and black spots all over it made me name it the Bruise-mobile. I promised to change the name when he painted it, but he ended up selling it. It was a great car.
I worked in the jewelry business for a while, and my next car was the right shade of green, so she was Emerald.
I do talk to my cars, but it's usually sweet talking them to try to motivate them to keep running for me. I never had the money for mechanics, so I needed them to run on loyalty.
