A Rolls-Royce Phantom was destroyed while trying to get shots of the van driving. It drove off a cliff. The stunt driver, luckily, was not hurt because he wasn't actually in the car. Producers still aren't sure how the car was moving in the first place.
The van broke mid-way through production and most of the driving shots are done without the van moving.
The van cost $1100 to purchase, $750 to fix so it could drive home and then break again, then sold to a salvage yard for $100.
