I love the Harry Potter books. I freely and openly admit it. I've read them all twice. The movies are pretty awesome, too. That having been said, I just had to add Mr. Weasley's contraband magical Ford Anglia to the series.
This was the car that Ron & Harry used to fly to Hogwarts in Chamber of Secrets. Fun fact; the original car used in the filming of the movie was stolen in 2005. Probably by a bunch of little Slytherin punks.
