Depends, I always thought that naming cars was silly, until I realized around my house all of the cars have a nickname, LOL.
My black 77 trans am- I simply call it the 'hot rod', during the resto my wife called it 'the p.o.s. in the garage', now she just refers to it as -'the tin can of death'.
She calls her new mustang-'baby'
I call our expedition- 'the van'
My son is trying to come up with something for his new GTO, I started calling it 'the yellow 'roo', that will probably stick, at least by men.
