This week on Car Talk, here's a new complaint for you: "My car is getting too many miles per gallon." Ephraim's fuel mileage doubled, right after he got engaged to be married, and he's wondering if it's a coincidence or if his fiancee has magical mileage enhancement powers. Meanwhile, the holidays mean more family gatherings, which mean more family arguments over cars. Al and his brother are sparring over whether it's possible to park a car so that you can't get out the way you got in; and, Sharon and her husband can't agree on whether it's safe to put a wreath on the front of her car. Also, a quest for heated seats, and if a Brigadier General wants to go 140 mph in a Crown Vic, who are we to stop him? All that and lots more on this week's Car Talk.
