This week on Car Talk, Dad gets equal time. Topher, whose daughter Rebecca rebelled against his strict record-keeping, checks in to explain the origins of his now-infamous little maintenance book, and whether Rebecca really is off the family payroll. Another follow-up comes from Car Talk's on-call chemist, Jim Davis, who's been in the lab trying to get Sprite to char a leather car seat. In new business, Cameron's got a starter that's been screeching for 8 months; Bill in Maine is hoping to get one working Probe out of the three in his driveway; and Episcopal priest Jep is wondering if he needs to grant absolution to the mechanic who may have messed up his timing belt job. And, from Germany, a fiery "Hey guys, watch this!" story. All this, and lots more, this week on Car Talk.
