I've only named one of my cars and its name came about in similar fashion as the picture in the OP.
My BMW 530i (white in color) has the original inspectors initials written in the engine compartment of VV. With those initials, I took the V and tied it to Helen Mirren's role of Victoria in the movie RED so the car's name is Victoria.
White on the outside, sexy body and a whole lot of power/whoop-ass under the hood.
