On inside of Paul Walker's wrist you can see his daughter's name Meadow tattooed there...no makeup was used cover it up
Early in the film the minivan shows the rear wheel thru the driver side mirror spinning in loose sand. The minivan is front wheel drive so the spinning should occur in the front wheel.
In the final car chase, just a handful of cars can repeatedly be seen as either traffic or cars parked on the side of the street.
Near the end of the movie, a man looks inside the minivan, and tells Michael to "Burn it all away!". Michael is played by Paul Walker, who soon after died in a car crash that set the Porsche ablaze. Incidentally, that car was red, just like the freshly repainted minivan.
The police cars are mostly BMW 3 series. There is also a VW Golf/Rabbit, and an Isuzu Pickup truck.
