Continuity mistake: At the start of the movie when the gun store is being robbed, one of them fires a portable rocket launcher at the police car, causing it to roll over and spin. As it comes to a stop just outside the store, it's visible that the driver's side window has been blown out, and the vehicle interior is visible, however when the same guy prepares to fire the bazooka to finish it off, the window has returned and is completely intact.
Continuity mistake: When the mayor turns up at the steelworks to speak to the boy about getting money, the limo has square headlights and white-walled tires. Cut to a few scenes later when Robocop 2 has already turned the limo over, the headlights are now circular and the tires are all black.
Visible crew/equipment: When Robocop visits Cain's hideout and sends his car in as a decoy, after he returns to the car, watch the driving shot closely. A wire has magically strung itself across the entrance and attached itself to the back of the car - it wasn't visible from an earlier shot. As the car drives forward it stretches the horizontal wire, and just as a tiny amount of pressure is exerted, the car explodes. Yeah, it's technically a mistake, but I think it's more worth checking out just to see how those tricky effects are achieved.
