Mine was named Godzilla--guy at the track came over to take a peek, with the 9 inch wide tires and ginormous splitter, he shook his head and blurted out, "That thing looks like....like...,Godzilla!" A few instructors were around and the names stuck. Once it's transmorgrified, I'm changing it's name to "Einstein". It'll all make sense eventually....
It'll be awhile before the car comes back, I'll finally get around to doing a build thread once it's all done, it'll finally be worth of one. The "Einstein" thing will make sense then, it's too good of a name to pass on, once I had this "other" idea. It's a perfect fit, most people will get it right away and smile (maybe even laugh), those that don't, should just by a Prius and be done with it. I actually never had a desire to put a name on my car until someone did it for me, now I'm ok with it. But I won't go any farther than that; unlike Dave, I have no plans in the immediate future to sleep with my car.
You could name it you favorite stripper / adult entertainer name. Or just MF, because when something goes wrong or a part fails that's exactly what you will call it.
