I don't know whether it is the same worldwide, but if a guy was asked the details of a car that was perhaps involved in an incident or something, he would probably be able to give a fairly good description such as Make, Model, Year, Colour, etc.
Whereas a girl would probably say "oh, it was a green one".
Anyway went to my local supermarket to buy my lottery ticket yesterday, and walked past a guy with 2 girls and overheard him say "I don't know what car I am learning to drive in, but it is a silver one".
Some guys are getting more effeminate by the day I think.
Sorry to any girls who are a bit more knowledgable, I am not being sexist, but just needed to tell this little story.
