This week's Car Talk strays into home improvement territory, but before Bob Vila gets his knickers twisted, we'll tell you the home is a 1986 Chevy C-20 Conversion Van. Matt and said van have taken up residence in a North Carolina parking lot. The bad news is, Matt still needs to drive it, which means fixing its nasty habit of stalling whenever he slows down. The good news is, since Matt's close to home (i.e. gainfully unemployed), he's a prime candidate for an on-air engine examination. It's a gripping two-part drama, in our 2nd and 3rd halves. Earlier, our Call of the week features Liz, who's ditched the carrot and just taken the stick to the shifter in her Subaru. Can Tom and Ray give her a more elegant way to get out of Park? Is she even interested in a more elegant way to get out of Park? Also, a brief foray into Philomedy, with some (insert your own adjective) philosophy-based jokes, and a new dealer service recommendation that screams "Boooooogus." All that, a new Puzzler, and lots more, this week on Car Talk.
