This week on Car Talk, Leanne is tired of shelling out 50 bucks per blizzard to escape her driveway, so she's trying to design a mini-snowplow for her Subaru. Leanne's husband thinks she's nuts, but Tom and Ray think she just might be the late-night infomercial's new best friend. Also, Jon's Toyota makes an explosive return from the Philippines; a new alternator puts an unexpected spark into Allison's marriage; and, Tommy embraces the Dark Side. All this, plus some creative personal ads from across the pond ("Shy, ugly man, fond of extended periods of self-pity seeks the impossible.") and lots more, this week, on Car Talk.
