[Dave McFly]

I was re watching Back to the Future (my all time fave movie) on a blu ray I got for xmas. in the 1955 part of the film when Marty is riding his home made skateboard and is chased by Biff and his gang. Biff's car switches from a 46 ford to a 48 and back again (most of the movie and in part II it is a 46) you can see the turn indicators move from the hood near the hood ornament (46) to below the headlights (47 and 48).

some others:

Passenger 57, Wesley Snipes character is driving a red Corvette convertible in a wide shot on the freeway it is a 86-90 style but when he pulls into a motel it is a 91-92 style (the horizontal trim that runs along the side and fascias of the body that are black from 86-90 are body color on 91-96 as they have different style 'gills' on the front fenders).

what ones have you spotted?
