This week on Car Talk, Terri's trying to convince her teenaged son not to buy himself a 1960's muscle car. Tom and Ray are ready to back her up with a trunk full of reasons why he's more likely to meet girls if he's driving a 1986 Volvo (with mis-matched hubcaps). But their efforts may all be undone when they turn to Tom's son Alex to back them up. Elsewhere, Deena's hoping a horn transplant will cause other drivers to mistake her Chevy Nova for a diesel truck; Thomas is wondering if his local Quickie Lube guy was just trying to clean out his wallet when when he offered to clean Thomas' fuel injectors; and should Roe tell the friend who loaned her his Civic for three months that she spent a good portion of that time driving with the parking brake on? All this and more, this week on Car Talk.
