Shortly after my previous message, Facebook changed the way they show pages statistics.
Now it is possible to have more detailed info:

13: Dodge Charger in "The Fast and the Furious"
6: Land-Rover 109'' Series III Station Wagon in "The Simpsons"
6: Pontiac GTO in "Knight and Day"
5: Ford F-150 in "xXx: State of the Union"
5: Subaru Impreza in "Banlieue 13"
5: Lincoln Continental Mark III in "The Car"
5: De Lorean DMC 12 in "Back to the Future"
5: Nissan Skyline GT-R in "2 Fast 2 Furious"
4: Ford Mustang Mach 1 in "Bullrun"
4: Mack RS-712 LST in "Shopping"

But these numbers do not seem accurate, as if you go on these pages you see that the counter is higher...
