Why are girls so interested in guys with nice cars?

I can guarantee that, since I have a nice sport car I am much more successful with girls than before. Women seem to be excited at the idea of it.

Even my female colleagues (with whom I always had a good professional relationship) ask me to pick them up.

Also guys like the car, but they only congratulate, they are not excited.
