This week on Car Talk, brace yourselves for another round of the Magliozzi Edition of "Too Much Information." In our first half, the brothers tackle such burning questions as, which one snorts? Does Tommy really have a PhD? And what's the deep dark secret behind Ray's Vermont-phobia? Then, it's on to Bradley, who's facing a costly repair - but since when does money matter, when smooth sailing with the in-laws is at risk? Got carbon? Kate sure does-- her Chevy Nova is filled to the gills with the stuff. Find out why her repair might require a search for a toothless, bald mechanic. Were Tom and Ray ever wedgied? In our second half, you'll hear the answer to this butt-wrenching question--and find out what happens when neglected wipers go whacko, and the possible causes of a squeal that started after a big repair. (Note: hosts reserve the right to resort to the Wheel of Misfortune.) Finally, hear the grim details of Tom and Ray's very first jobs- and their current hobbies. In closing, we ponder how its possible that one particular auto company still hasn't figured out AC after twenty years, and what would you do, if your mechanics went on a little road trip with your car. All that and more, this week on Car Talk.
