This week on The Best of Car Talk, Danni bought a used Range Rover in the midst of what she calls Pregnancy-Induced Insanity. Reality quickly set in, as her skyscraper-esque husband couldn’t fit in the car, and it racked up a few thousand dollars in repair bills in no time. Should she cut her losses and dump this impulse buy? Elsewhere, Charlie had to replace his fuel pump three times in the last year, and is tired of having them fall on his chest; Kristy may need a stethoscope and a potato to figure out why her car is making noise; and physicist Robert is too busy trying to solve thermonuclear fusion to get his timing belt changed. All this, plus the tale of Sonja Henie’s Zamboni, and lots more, this week on The Best of Car Talk.
