Yes it will break. I was a Carmax last week looking at Boxster's and while putting the top down it didn't fold right and cracked right up the middle. If you just stop about half way and fold it yourself then put it the rest of the way down it will work.

edit* I reread your question and it is supposed to fold right in the middle but you have to watch, your problem is when it doesn't fold.
