This week on Car Talk, Kerry's Boston condo came with one unfortunate feature--a large crater in the parking lot that fills with water every time it rains. She's worried that driving through this "pit of despair" every day is killing her Honda. Are those fears warranted, and does Kerry need the number for Vinny's Late Night Concrete Services, Inc.? Elsewhere, Vincent "inherited" his daughter's Jeep, along with its tendency to shake, rattle and die above 2,000 RPM; Ben needs help convincing his girlfriend that cars are impervious to wind chill factors--especially German cars; and on Stump the Chumps, we find out if Tom and Ray helped lead Kathy's son to victory in the Pinewood Derby--and, why they didn't. All this, and lots more, this week on Car Talk.
