In the scene just after Kate Brewster's dad has been shot he says to go to his office. On the way there you can see his jacket is undone and you can see his shirt and tie. Yet when they enter the office it shows him sitting down with his jacket neatly buttoned up. For a guy who just got shot and is running from machines, I doubt he would worry about buttoning up his jacket.
The hubcaps on the hearse come off but are back on in later scenes.
In the cemetery scene when the Terminator uses a bazooka to fire a missile at the TX, the shot that shows the TX being launched up in the air and hitting a gravestone should have shown the car used by the TX and the road where the car was parked. In the next shot, when the TX gets up and starts to run after the hearse, the road reappears but not the parked car.
In the scene where John & Catherine are in the hangar at the runway, the Cessna's tail number is N3035C. When the plane is shown in the air, the number is N3973F. When they land, the tail number has changed back to N3035C.
During the shooting scene at the cemetery, note one of the stones (rectangular from the left) behind T-101 when he comes out carrying a coffin. You can see it has 5 holes - 3 left, 2 upper right side. However, a few seconds later, it has 6 holes, but their position has completely changed, 3 upper side, 3 right side.
