Wow, this is an easy one. I can answer this ... So ... some POS bags my car ... I act surprised and say, "Oh, you've driven one of these then?" They invariably answer, "No". I then say quite matter of factly, "Well I've driven a few just like yours." Then I wait for a couple of seconds ... (the pregnant pause) ... and then add, "which is why I decided to buy this". Shuts them down and they never have a comeback after that.
