At the very end of the movie before the credits
start to roll, Poole walks by his Ferrari.
You can clearly see there's no car parked behind
him. He finds an envelope on his windshield
containing his keys and a letter saying tax free.
NO ONE would leave a Ferrari, top down, parked
on the street with they keys in an envelope!
Poole gets into his Ferrari, says he loves this
car, then backs up into another car.
Remember, there was no car parked behind him.
There was nothing behind his car at all. You seen
this when Poole was walking past the Ferrari.
