This week on Car Talk, we revisit a caller's unexplained electrifying vehicular event. Was it an atmospheric abnormality? A UFO? Beam 'em up, Scotty! Then it's warp speed to Georgia where Caroline has another curious conundrum: has a car alarm mysteriously installed itself on her Saturn? Elsewhere, Libby is looking for the perfect car to run away in, and Bob is in dire need of marriage advice. Could the turn signal hold the answer to marital bliss? All that, plus a new tantalizing puzzler from our Travel and Leisure series, this week, on Car Talk.
