We're all getting older, so as a public service, this week on Car Talk we update a few classic songs to reflect our demographic shift. For example, "I get by with a little help from Depends." In matters automotive, Mickey's Nissan sounds like it's getting a wedgie whenever he turns on the AC, and a recent fender bender has Stephanie worried about passing an upcoming smog test. Also, Lisa's looking for help trying to convince her husband to rent  an RV for a road trip to Graceland, and Doctor Rich's new cigar habit's given him both a stinky car-- and a nasty cough. And, what bad advice could leave Sally with a tombstone reading "She died getting 95 miles per gallon"? All this and lots more, this week on Car Talk.
