This week on The Best of Car Talk, Tom and Ray unveil a new strategy for stubborn callers. If they can’t diagnose Laraine’s noisy Acura, can they browbeat her into changing the symptoms? Elsewhere, Richard’s Land Cruiser is shooting flames out the tailpipe, which could be a cause for concern or a chance to have some fun. Also, Julia is about to own her first car, and wants to know how to take care of it, aside from walking it twice a day; Dorothea’s mechanic wants to run a psychedelic blacklight test to find her Volvo’s oil leak; and should John clean his car before a first date, or let her see him for the slob he really is? All this and more, this week on The Best of Car Talk.
