Such a fun experience! We've gone twice, and both times were enjoyable. The free tour is great, but very long and unless you're a big car person, you may find yourself a little bored. The man giving the tour was very informative and knew a lot about the cars and Shelby as a whole. The best part is going in to the factory. A designer actually gave a spiel to us this morning about his work, and you even get to see and hear some of the amazing vehicles!
