The car has been rammed off the road from behind by another vehicle, but when the back of the car is shown, there is not a scratch on it. No, not necessarily. It hit the bumper, which is what they are there for.
The garage in which the big white transit van is supposedly normally kept is way too small, only big enough for a small car.
When Aiden and Vera are the garage (approx. 52 mins), on the left (looking into the garage) shows a lot of clutter under the red mark. Then looking out of the garage (under the red mark), there are only a few petrol cans.
