High-end vehicles that are stolen like this are more likely to be kept fully intact and then transported out of the country in a shipping container less than 24 hours after they're stolen.
New Jersey is a sh!t-hole in many ways, but law enforcement is usually on top of these things. As soon as that situation went bad at the mall, those two mutants knew damn well that they had to abandon the vehicle because the police would be all over Port Newark/Elizabeth looking for it among the outbound container shipments.
Ah so! Thanks for the explanation! Now, it all comes together for me. I own three cars but know absolutely nothing about cars!
