This week on Car Talk, Judith's trip home for the holidays got a little more interesting when the transfer case in her Mazda exploded, sending flames into the car, and melting her brake pedal. Happily, Judith escaped injury, but she's calling in the Car Talk forensics team to try to figure out what happened. Meanwhile down in Alabama, June is using her Jeep to off-road--over the speed bumps in the parking lot at work. Is she doing more damage to the car, or her teeth? Also, on Stump the Chumps, we find out if Victoria went car shopping for her three sons, and career shopping for herself. All this, a puzzler from the high-speed chase series, and lots more on this week's encore edition.
