This week on Car Talk, LaDell's new career as a car salesman was off to a good start, until  he opened his mouth. He bragged to a customer about a car's torque and horsepower, the customer asked LaDell to explain the difference… and he's still waiting for an answer. Elsewhere, Liberty's Nissan is sending a clear message: Give me new ball joints, or I may give you death; Tony's 17-year-old son says the fumes from Dad's Saab are responsible for him dropping AP history and not cleaning his room anymore; and, Liz is wondering whether her trusty old Toyota truck can serve as a two-story home for her sled dogs. And, from our Expository Writing Department, we have a few choice metaphors and similes, including, "He fell for her like his heart was a mob informant, and she was the East River." All this and lots more, this week on Car Talk.
