This week on Car Talk, Linda's husband proudly told her he'd "fixed" her Volvo--by cutting the roof off and turning it into something resembling a convertible. Is her car still safe to drive, without a football helmet? Meanwhile, Jeff relocated from New Orleans to New Mexico, and the higher altitude is wreaking havoc on his automatic breadmaker. Apparently Martha Stewart's line was busy this week, so we'll see if Tom and Ray can bring some life back to his loaves. We've also got a few bona fide car problems: Robert's Subaru keeps overheating, despite him replacing just about every part that could be responsible; Gary wants to know if he can take a 1300-mile road trip, all while down one cylinder in his Isuzu; and on Stump the Chumps, we find out if Tom and Ray correctly diagnosed Anne's growling minivan, and if her husband's vasectomy reversal has been fruitful. All this and lots more, this week on Car Talk.
