Factual error: The Douglas firs or Redwoods shown at the front of Longbourn (Groombridge Place) were not introduced to the UK before 1827, but the film is set in 1797.
Factual error: In the scene during the first race with Matt Dillon, right after he spins Lindsay Lohan out, she grabs the gear shift. We see "magical electricity" head down the shaft and forward into the engine. But, the engine on Bugs is in the back. In other scenes, it is confirmed that the front hood on Herbie gives access to a trunk and not the engine.
Factual error: When Fabrizio arrives by ship you can see the cooling water jet coming out of the boat.
Factual error: The oldest of Frank's sons has the other five boys lined up facing him. He issues the command, "About face!" Each of the boys makes a quarter-turn to the right, which is "right face", not "about face."
Factual error: In the web chat you can see the term 500 mbps on her streaming. That's far higher than any realistic speed for that time and place, and way above what's needed for web chat anyway. (00:22:50)
Factual error: Maggie magically overcomes her disability in a single session of reading a poem.
Factual error: When Helen is leaving church, she says it's April 25th. In the movie, the year is 2003 (you can tell because she writes dates in her diary). April 25th in 2003 was actually Friday not Sunday.
