['My daugher will turn 16 next month and I cannot wait!!', 'Oh wow! I bet she and you are so excited about it!', "We've been working on a car for her for almost a year now, getting it ready and restoring it.  Cannot wait to give it to her."]
What a nice surprise that is! I bet you anticipate her to love it!
My daughter will turn 16 next month and I cannot wait!  We are giving her a new to her car that we've been working on for almost a year now!
