This week on Car Talk, Sherry and her husband discovered they couldn't mount their bike rack on the roof their new Lincoln Town Car. How are they going to haul around their kids and bikes? His solution is a Minivan. Hers? A Town Car Stretch Limo. Can Tom and Ray bring a return to domestic tranquility? Elsewhere, Michele's husband thinks she has too many keys dangling from her ignition, and has made the most dire threat: either she divests of a few keys, or his Mom's moving in with them. Also, just a few weeks after a Freon refill, Michelle's Escort's back to blowing hot air; Brad's adding an alarming amount of fluid to his Camry's clutch; and Pradeep is being slowly driven crazy by the cell phone he dropped into his BMW's duct work. Will Tom and Ray have any suggestions for removing it that are more helpful than, say, turning the car upside down and shaking it? All this, and lots more, this week on Car Talk.
