This week on Car Talk, Tom recounts a day that will live in Magliozzi family infamy-when Ray sent his beloved 1965 AMC Ambassador, a.k.a., "The Sleek Black Beauty," to the crusher. Elsewhere, Ron's check engine light has been on for 75,000 miles, and he's beginning to think it might be time to figure out what's causing it; Ellen's looking for an intervention to help cure her fiancé of his non-stop shopping for performance add-ons for their Blazer; and, can Casey's career as a bagpipe maker help rid his car of garter snakes? And, from the Department of Gender Numismatics, why do women pay for things with change and men don't? All this and lots more, this week on Car Talk.
