After the fast food joint is robbed, the rear window of the getaway car is shot out, but in subsequent shots it is still intact.
During the robbery, Suzy has the bag of food in her hands as she walks to the back of the store to tell #3 to hurry up. When she is seen next entering the office the bag is missing.
Before they go rob the fast food place, they run into a semi which breaks their taillight. After they rob the fast food place, they leave and you can clearly see that the taillight is still intact. Later in the movie the taillight is broken.
