This week on The Best of Car Talk, Steve needs help adjusting to a life with four cylinders and cloth seats, after his recent divorce forced him out of his Ferrari and into a Camry. Elsewhere, Deirdre's mechanic has a hair-brained scheme to weld new teeth on her Volvo's flywheel. Is it worth doing, even if it's just for laughs? Also, Connie needs help choosing the right car for her road trip to Rio de Janeiro; Daniel needs to stop replacing distributor caps, and replace his mechanic, if he wants to find out why his Sentra stops running; Piali's best response to her squeaking steering wheel may be a swear box; and is Lyle's strategy of putting a pizza box in front of the radiator a boooogus way to warm his car? All this and more, this week on The Best of Car Talk.
