This week on The Best of Car Talk, Karen’s mechanic may be taking period authenticity a little too far by refusing to install shoulder belts in Karen’s new vintage Rambler. Elsewhere, Ron tried to find a vacuum leak with propane, and now has two fewer eyebrows to show for it; the VW Westfalia Josie inherited from her dad has been starting and wandering off on its own; and is that 150-pound log Lucia put in her Corolla’s trunk, to stop it from fishtailing on the ice, doing more harm than good? And, are remote starters contributing to the decline of Western civilization? All this and more, this week on The Best of Car Talk.
