The engines in the beginning of the film are as clean as mine and the tyres look new, on the cars in the workshop if not the ones in the yard.
It's a demo film made with new cars. Look how slow the throughput is. Not a production facility. The out-of-date models shows the film age. Coolant contained blue antifreeze. Some of the vehicles had unused-brake disks, though I also saw some used ones.
The ones we saw actually being cut up and crushed at the end were much older. Strange that they crushed the shells with seats, glass and plastic trim still fitted.
Interesting to see Borat working there.
