This week on The Best of Car Talk, gather round for the greatest road trip story ever told. Dave and his girlfriend drove from Alaska to Minnesota in an overheating Chevy Cavalier with an old campfire grill jammed into the catalytic converter, a crescent wrench with no sockets, and one big zit on Dave’s forehead. In more mundane matters, Patrice’s VW bus won’t start, John Mark’s backseat passengers are getting their feet soaked when he makes a turn, and Alana’s gas tank is spitting fuel back out after she fills it. Also, how should Rich wake up a Buick that’s been napping for four years, and is the threat of fire enough to convince Jim that replacing his tailpipe might count as a “necessary repair”? All this and more, this week on The Best of Car Talk.
