Summary: <p>This week on Car Talk, Jim is wondering why his mechanic billed him for 8 hours of labor on a job that took only 4 hours, thereby launching a Magliozzi explanation of the mechanics' space-time continuum. Elsewhere, Lewis' VW dealer refused to honor a warranty repair, but may re-evaluate his position when he learns Lewis is an IRS agent; Abbie's friend gave her the most wacko suggestion we've ever heard to fix her car's alignment; and can Rachel hold us liable for the fender bender she caused because she was laughing at Car Talk? And, on Stump the Chumps, we find out if Tom and Ray helped put out the fire in Red's convertible, or if they just fanned the flames. All this and more, this week on Car Talk.</p>
