This week on The Best of Car Talk, Jackie’s pet python’s lunch disappeared into the vents of Jackie’s Explorer. Not a big deal, right? Well, lunch was a live rat which has since deceased, but is still in the car stinking it up to high heaven. Elsewhere, Delena has decided that six years is long enough to live with an oil leak, so she’s ready to have it addressed; Helen needs to stop and sniff the tailpipe to try to figure out what’s leaking from her Odyssey; Rich may need a team of FAA investigators to help decode the noise coming from the black box in his pickup; and, a tale of a Fiat’s Christmas miracle. All this and more, this week on The Best of Car Talk.
