This week on Car Talk, Andy borrowed his Dad's Buick for a romantic drive to the country. All was right with the world, until he ran out of gas. A Good Samaritan gave him a few gallons, but somehow Andy managed to drop a straw into the gas tank. Now, Dad's car is running lousy, and Andy needs to know if one straw could cause a few boat payments worth of damage. Elsewhere, Brian is trying to decide whether his Mercedes' new noise is the sound of it playing Taps; Mary wants to coax a few more miles from her Altima's slipping clutch; and Gail wants to retro-fit a vintage VW Beetle with air conditioning--maybe a nice window unit from Home Depot? Also, on Stump the Chumps, did Tom and Ray successfully diagnose Susanne's overheating Mazda? All this, and lots more, this week on Car Talk.
