Your daughter and my daughter would have a blast. My daughter has done all kinds of stuff on the car. She used to follow her daddy around and make him show her how to do things. I don't think she has torn down the engine but she has replaced the timing belt and brakes. She does her own spark plugs and oil changes, too.
One time the two of us were out and the car had a flat tire. We looked at each other and figured we were up to changing it. We did. About the time we jacked it down some man came along and asked us if we needed help. NOPE. We got it. Well we jacked it down all the way and the spare was flat too. No cure for that one. DH was in the dog house a while though.
