A bit of insight, coming from a guy who actually got burned on a double sale of a white hat special '69 Charger, years ago;
Forget about the car.
I know you've known of the car for a long time, but you need to get your head out of it. Here's why;
You can spend tbe same money on another car as nice as that one, but suits your tastes in year, make, model, drivetrain, color and budget. You can, include your friend in the hobby and have someome to work on cars with, along with your daughter, you won't be rushed to buy something sub-par in any way, your daughter can have a stake in which make/ model/ year/ drivetrain to go with, per her liking and needs, along with yours and you will ultimately end up with something better for you, and your daughter.
Without coming off brash, I would like to suggest that you buy a commuter for your daughter in a year or so, when she is ready for her permit.
I restored the body, interor, brakes and engine on a '62 Studebaker Lark Cruiser, for my bosses daughter, intended for her to drive as her first car. While she was extremely excited about it and wanted to drive the Lark, her mom insisted on a car with more SRS junk, so they bought her a newer Chevy Aveo. So, far, she's 17, has 3 traffic tickets and has rearended two cars. Not enough to trip the airbags, but while I know that people learned on '60s Darts to drive in, there are a lot more people on the road, today, and with none of the schools offering driver's education, let alone as a requirement, it would be a wise choice not to put a novice driver behind the wheel of a surviving, classic car, or even a restored ine, until she has had practice avoiding a few accidents, along with the basics.
I'm not suggesting that she will be abad driver, by default, but I am stating that she will be involved with bad drivers, inherently, fir the reasons above, and I know that even when I took the wheel for the first time, I had to learn how to anticipate other people's shady driving habits, in traffic, doing **** like watching tire proximity to the lane, mire than looking for turn signals, from people not using them on a semi-regular basis, etc. Things they don't teach, that you either learn subconciously, or realize it and make note, the easy way, or the hard way.
Get a beater, let her drive it to school and work while you both dump money and time into something, to get it done right, without downing her transportation all the time, to perform ritual things, like front suspension rebuild, trans clutches, leak fixes, performance mods and other typical operations that require not driving the car for runs of time, when it's not all simply done at first, if you're driving your project.
