This week on Car Talk, after four years of relying on the laws of physics to parallel park, frustrated New Yorker Dan wants to know why his Jetta won't go in reverse. Also, a novice driver searches for her perfect entry-level vehicle, with just a few criteria: small, safe, reliable, cute, and cheaper than 5 grand. Will she be shopping in Automobile Never Never Land? Meanwhile, out in Ohio, Anna may need to take a hose in the left nostril to track down the gas leak in her hand-me-down Maxima, and on Stump the Chumps, we find out whether Tracy was able to rid her block of an unwelcome guest, and still sleep at night. All this, plus a puzzler from the Exponents and Existentialism series, and lots more, this week on Car Talk.
