This week on the Best of Car Talk, Tom and Ray wrestle with a textbook case of Extreme Frugality. Susan’s husband loves his old Volvo so much he refuses to use the windshield wipers so he won’t wear out the motor. What’s next? Preserving the brakes by not using them? Elsewhere, Jackie needs help deciding whether she should buy a beater car for the winter but her Dad has recused himself after a run of recommending lemons. Also, something may be wrong with the air conditioning in Bill’s Explorer (the smoke billowing from under the hood tipped him off); and on Stump the Chumps, we find out if Carla’s truck is still only able to climb the hills of Homer, Alaska in Reverse. All this and more, this week on The Best of Car Talk.
