we have all girls names for our cars:
Cobra's Contour is named Tracy, because she traces the curves in the road.
My 'tour is Natalie (this reason is a weird stretch, so bear with me) Paint code is Portofino Blue. Portofino reminds me of Portman, and I <3 Natalie Portman.
My Cougar is named Pirotess, because she's sexy and Pirotess is a sexy character from an OAV series I enjoy.
Our F350 is named Joanie, after Joanie Laurer/Chyna Doll (the wrestler, VH1'S Surreal Life), cuz Joanie is a huge lady, and so is our truck.
I forget what he named the motorcycle, but when it's officially mine, I'll have to rename it.
