Factual error: Whenever they open the trunk of the Eldorado, it acts and sounds like there is a push button. In fact you have to use a key to unlock and open the trunk.
Continuity mistake: When Paul Rodriguez and one of the mafia guys are in Paul's truck, you can see sky and a mountain range through the rear window when the curtain moves. The truck is pulling a trailer full of cows at this time so you should not be able to see scenery out the back.
