Embedded Player This week on The Best of Car Talk, Dana's Jetta jerks in 1st Gear, and Tom and Ray have a highly technical explanation. Elsewhere, Mark thinks his "straighten the curves" driving technique is more efficient and saves wear and tear. It's also driving his wife crazy, which may be another plus as far as Mark is concerned. Also, Suzy checks in with the final report on her attempted drive across Mexico in a VW Vanagon; Andy felt like he was driving naked and after confirming he was wearing pants, determined his automatic seat belt wasn't so automatic anymore; and Joddy's (yes, that's how he spells it) Chrysler dealer says it will cost $300 to replace a missing nut, which is well, kinda nuts. All this and more, this week on The Best of Car Talk.
