This week on The Best of Car Talk, Beryl won custody of her husband’s old Mercedes in their divorce. She loves the car, but may be moving from Texas to the Great Frozen North and isn’t wild about driving it in the snow. Should she dump it, put money into making it safer, or follow Tom and Ray’s Plan C? Elsewhere, Tony’s Chevy may have tried to kill his mother-in-law with brakes that didn’t brake; Ginny and her husband are arguing over the best way to avoid croaking frogs on the road; and Ellen’s mechanic says her oil has the smell of engine death. Is he really smelling the oil or just his cologne? All this and more, this week on The Best of Car Talk.
