This week on Car Talk, one listener's tribute to Tommy's dearly departed Dodge Dart will have William Wordsworth rolling over in his grave. "For in the spot where Dart once sat, there's now but oil stains." Later, Tom and Ray try to rescue a spoon trapped in one car's vents, and a 20-dollar bill trapped in a driver's door; and, on a slightly more urgent note, they try to keep Eric's engine from disintegrating. Elsewhere, Doug might become the Chuck Yeager of CV joints if he doesn't mind the risk of getting stuck on a railroad track; and can Environmental Studies major Carl do anything to ease his guilt over driving two ginormous gas guzzlers? All this and more, this week on Car Talk.
