Your friend cameron just bought a top-of-the-line mountain bike and paid with cash, like dave recommends. he listed his old one online. a buyer expressed interest in the bike. you heard cameron describe the old bike as “like new.” you know that the bike’s front-wheel fork once snapped and had to be welded. with new paint, the weld is invisible. the buyer passed, but you remind cameron what dave teaches about buying and selling bargains. what did you tell him?
