Pardon the intrusion. Can't keep quiet on this one....
Plan A is now:
Keep the Z4c for yourself.
Buy her an e36 318is/i Manual Tranny, for example...
Plan B: Give her the Z4c as a graduation present, like from college!
TEACH her to DRIVE first with a manual tranny.
It will be more fun, she'll be cool because she learned a skill from Daddy, easier car to handle/ not too much power, still a safe cage, Less Chance to drink lattes and text.... it may save her life!
