Also tell her that your parents' marriage is the most visible model of what marriages are like, and maybe that model isn't going to be the best one for the two of you, but it is where you're starting from. Tell her what parts you think are good, and what parts you want to do differently.
Ask her what her model of a marriage is. Is it based on her parents', or on something else. Ask what things about it she things you two should keep, and what things she wants to do differently.
That may be a very productive discussion for you.
