When the team are modifying the van, they cut the front grill away but the logo is Chevrolet and not the well-known text "GMC". When they have finished, GMC is visible again in the next scene. However, when they remotely activate the machine guns, the Chevrolet logo has reappeared.
The scene of the car chase where the A-Team tries to escape from Colonel Decker and his men by jumping over the construction site is actually copied from episode "Labor Pains" (#2.08). In that episode this scene also marked the end of a car chase with Decker.
When the bounty hunters open the back of Kelly Stevens' van and are confronted by the barking dog, you can briefly see a bare arm appearing to hold the dog back. It's not Murdock's arm, as he is wearing his usual leather jacket.
