This week on The Best of Car Talk, Cathy thinks she may have found Mr. Right, but he may not live to see their wedding day if he kills her Sentra’s clutch. Can a few well-timed dope slaps save Cathy’s car, and the relationship? Elsewhere, Nicki gets a primer in how to shop for a used truck, including wardrobe tips. Also, postal worker Jess’ car has gone, well, postal when coasting to a stop; Randi is slowly being driven crazy by a golf ball rolling around in her Volvo; and Ken’s mooing Ford qualifies him for the Car Talk Cockamamie Answer of the Week. All this and more, this week on The Best of Car Talk.
