This week on Car Talk, Brent tried to start his girlfriend's Mazda, and wound up with the car, and his relationship both burnt to a crisp. Can Tom and Ray tell him where he went wrong, with the car or the girlfriend? Elsewhere, Ellen's very generous neighbor keeps giving her cases of undrinkable home-made wine. Can she put it to use as windshield wiper fluid? Also, Shelly's bad day at a casino got even worse when her car died on the drive home; and loyal delivery man Steve is suffering a severe case of "New Parcel Truck Envy." Will Tom and Ray help sabotage his old reliable truck? All this and lots more, this week on Car Talk.
