Getting Off - S4-E16
Continuity mistake: When Jamal is been helped out of Ed Burnell's wrecked BMW 7 Series, the wrecked car is a late 80s-early 90s E32 model.

Other mistake: When Grissom's vehicle is shown driving to Jackpot, Nevada, he is shown to be driving on the wrong side of the road. (00:03:15)
