When the brakes fail and Higgins crashes the Ferrari, it is clear throughout the entire sequence that the right (passenger) side of the car sustains all the impact. In fact, during the credits, the last scene which shows a close-up of the crash, reveals that the left (driver's side) is perfectly undamaged. Yet, when the car is on the rack, being examined by the mechanic, the driver's side is shown with significant damage.
When Magnum is getting back the keys to the Ferrari from Higgins, he is wearing his Tigers cap, but when gets to the van, he is wearing a different cap.
