We're trying to sell the car so we had to remove a dent, a scrape and a scuff. A guy I know and trust wanted $350 but his schedule was too jammed, so last weekend I went with a mobile auto-body team -- a couple of 30something guys from back east. One of them, a stocky, fast-talking, type-A dude, called himself "Charlie" but his phone ID read "Nicholas Grant" -- a red flag.
