This week on Car Talk, Sasha learned a new recipe for dealing with a radiator leak--add black pepper and eggs. Did this combo save his engine, or at least provide brunch while he waited for a tow truck? Elsewhere, does Chip need to resort to "tailpipe diplomacy," in the form of a cherry bomb, to get his neighbors to stop warming up their cars for 20 minutes every morning? Also, Bill and his wife are looking for a $700 car that makes them look eccentric rather than cheap; Jennifer's good deal on a used Volvo may not have been so good; and can Tom in California adjust to his new life as a car salesman without succumbing to the white belt and shoes? All this, plus one tourist's eye-opening visit to Car Talk Plaza, and lots more.
