Yeah, the quote in that article...
Those of us who watched could not hear all of the conversation, but did catch the large flatbed truck circling the block with a DeLorean while Seinfeld and Oswalt commented on the compromised status of their ride.
...makes me think that the car broke down. If that's the case, good grief. Why does this consistently have to happen to DeLorean's; especially when being filmed for something. Fingers crossed that I'm wrong.
