This week on Car Talk, you'd think twin brothers working in the same garage would have the same auto-diagnostic skills set, right? Well, Becky in Dallas is learning the hard way that it ain't necessarily so, after letting the wrong twin get his hands on her Lexus. Meanwhile, Craig in Maryland wants to spend 10 grand fixing up his beloved Camaro, but will the chance that he'll have to tack on the cost of a divorce change his mind? Also, on Stump the Chumps, we find out if Teresa in Minnesota really was being tailed by Black Ops helicopters, or if something more mundane was causing the noise in her Escort. And, how do you recover from a car prank delivered via Post-It? All this, plus a new puzzler from the Travel and Leisure series and more, this week, on Car Talk.
