My Uncle the Car is the fourteenth episode of the third season and the 59th episode overall.
Will chides Grace for owning an old car "with no A/C and 'old-man stink'," so she lets him sell it. But when she decides she wants the lemon back for sentimental reasons, it proves difficult to retrieve from the quirky buyer, Sister Louise. Meanwhile, a cryptic postcard from his mother convinces Jack that he's half black. And when a fellow trophy spouse tries to steal Rosario, pool shark Karen challenges him to a game--with her trusty maid as the stakes.
