I went to the link provided by jobob - pedalfaster, I once owned a 1969 VW Transporter with some Westfalia bits in the rear and her name was Esmerelda!!

I used to call my mtb Fleabane b/c it was the exact color of the flower. It's since been re-powdercoated and hasn't gotten a new moniker yet. My road bike is nameless. My fixed gear/scorcher is "Scorchette", which I also use as an internet handle.
