This week on The Best of Car Talk, Joanna's 16-year-old son is ready for his first car, and what could be better than a vintage ice cream truck, complete with a working freezer and music?! Should Joanna buy the truck, and thank her lucky stars her son didn’t ask for a Viper? Or is this aging freezer on wheels one push pop away from a disaster. Elsewhere, Sarah discovered that she can’t get her dome light switch to work unless she pours water on it; Bear’s 100,000-mile plugs have become 200,000-mile plugs after fusing themselves to the engine block; and Juliette’s timing belt may be hanging on by a thread. Also, on Stump the Chumps we find out if John cleaned up his act and his disgustingly messy car for a date. All this and more, this week on The Best of Car Talk.
