Continuity mistake: When Paris was on the phone to Janet in the Gas Station (the episode where they work at the gas station and meet "Chops" and co) it cuts to a shot of the fat boy standing next to the same phone and the receiver is put down. It then cuts back to Paris using the phone.
Continuity mistake: While Mike is cleaning out the armadillo's hay, just before he finishes the second one you can see the amount of hay in the bin is a few inches from the top of the bin.

Continuity mistake: During the police car challenge, Richard Hammond is taking his homemade police car around the track on a timed lap (with extra points for flamboyant driving). As he rounds the Hammerhead corner, the makeshift stinger (that's a spike strip for the colonials) on the front of his car breaks off and is left behind. He then drives through a stack of boxes, getting one caught on the remains of the stinger mounting. As he approaches the second-to-last corner, the box has gone and the stinger is now back on the front of the car. In the final shot as his car limps across the finish line, the stinger is once again missing and the box has returned. Clearly footage from a different lap was substituted in. (00:51:10)
