This week on Car Talk, Wendall's Bronco burst into flames and was burnt to crisp, right after a 200-mile drive. Was it electrical? Fuel? A spouse holding an insurance policy? Elsewhere, Barry is hoping to find true love by fixing his co-worker's windshield wipers, and avoiding her jealous boyfriend; Donna needs a gracious way to tell her husband his theories about keeping her gas tank full are "boooooguuss"; and Deborah's lurching efforts to learn to drive a stick shift aren't being made any easier by her Civic's loud whine. Also, on Stump the Chumps we find out if Farmer Ben's manure spreader helped get his truck running smoothly again. All this, and more, this week on Car Talk.
