Great

i just took the screenshot a couple seconds earlier when he's trying to catch up to the Malibu: http://www.imcdb.org/vehicle_11602-Chevrolet-Malibu-9C1-1980.html

I have the DVD too, but if you have time you can check, sure

antp..i have my BTTF DVD and i'll check to see if there's another shot for the cop car.

Look right to me. Thanks!

make sure i did them right:

I suppose that there is no other view of that Datsun. Maybe I should try to find another one for the police car then.

NOTE: #1 is the same shot as: http://www.imcdb.org/vehicle_11602-Chevrolet-Malibu-9C1-1980.html

How is this handled?
