This week on Car Talk, Mara has tried everything to rid her car of its ant infestation. Well, maybe not everything, since there are no burn marks. Tom and Ray have a way to lure them out that is at once incredibly creative-- and very stupid. Elsewhere, how does Diane reconcile her husband's desire to rebuild his BMW with her parent's need to get it off their farm, so the potatoes can be planted? Also, a lesson to car dealers: if you're going to make up a name for your wife, choose one you know how to spell. And, on Stump the Chumps, we find out if Tom, Ray, and Joan's husband correctly diagnosed her screeching Ford Festiva. All this and more, this week on Car Talk.
