Possible M2 Machines box error

I lucked out and was able to find a M2 Machines chase piece. Although I didn't take any pictures, I opened a sealed box straight from the pallet. The odd thing is, the box says 7,800 pieces, but the car on the inside is the 750 pieces chase.

I know for a fact that this pack is not altered, due to the next two pictures. The tape does not appear to be tampered with.

This is one of the joys of diecast hunting, you never know what you'll find. Okay time to go eat some PEZ candy, happy collecting!
