As everyone's token "car person," sometimes you reach a point where you just get tired of being the universe's personal vehicular helpdesk. Let me help you with that.
Maybe you've tried time and time again to correct some nonsensical beliefs and ran out of patience. Maybe the person in question can't figure out The Google, and won't use it to look up total softballs like specifications and reviews. Maybe you just know—within the dark, cold depths of your hardened soul—that no matter what you tell them, they're going to end up buying whatever they wanted to begin with, and that it will be something horrible. Or perhaps they're considering...a Camry.
