Continuity mistake: During the Nascar race, Maggie passes the 48 (Lowe's) car twice in the same sequence. Only the front corner of the Lowe's car is visible when she passes it the first time. Then the shot cuts to her dad praising her on the walkie-talkie. When the shot cuts back to Maggie racing, the Lowe's car is passed again.
Continuity mistake: In the scene when Lindsay left Herbie to race in Trip's car, Herbie is shown to have a piece of clear material on his back revealing his engine. In most other shots, he doesn't have this. This is especially noticeable when he is being put into the garage, after the car crash he was put through to destroy him.
Continuity mistake: Herbie is seen from the back as Matt Dillon beats on the hood and right front fender using a tire iron. When the camera angle pans to the front, there is not even a scratch in the paint, let alone a dent. Herbie's "magic" apparently didn't prevent sheet metal damage as seen in several after-race views.
Continuity mistake: When Herbie is looking at the new yellow Volkswagen, his windshield fogs up. Then a clear spot shaped like a heart appears in the middle of his windshield. But then when it switches to the shot of him moving over to the yellow bug, the heart is at the very right of his windshield (from our view.).
Continuity mistake: In the scene where Maggie and Kevin are washing Herbie, Herbie wiggles and shakes off the water and soap. Maggie and Kevin turn once in a zoomed out shot after Herbie splashes them, and turns a second time in a zoomed in shot of them.
Continuity mistake: When Maggie is first boxed in during the NASCAR race notice the entire pit crew is shown in a line reacting to the action. Seconds later when her father appears among them they seem to be standing in a different location with only Kevin and Ray Jr. there with him.
