Right. As Marty McFly goes around the corner, the side of the Datsun 1200 is in the background (fuzzy). About 10 seconds later, you clearly see the white Coupe behind the "Hill Valley" sign. And then to top it off, another Datsun pulls up behind (it's a yellow B210 2-dr sedan, more clearly seen at 11:42 when Marty catches a ride behind the police car).
Bonus: at 9:00 as he's walking with Jennifer there is a emerald green B210 GX Coupe in the lot with license plate "FOR MARY" and the red Z is now in the parking lot
