Wait what? You bought a *new* car? Why not get a 2nd hand (4 or 5 years old) from a decent dealer instead? Preferably one with a guarantee so if you find a major "engine fault" you can take it back?
I know it's a bit late now, but have you worked out how much you'll lose on depreciation alone on that car?
As far as waiting for 10 years to give it to your daughter, have you considered how much maintenance/repairs would be required for a 10 year old car? It might not be so much a "gift" as a "worry" - oh no, is it going to break down when she needs it most? I can foresee in 10 years you buying her a newer second hand car, I'm sorry to say :(
Regarding bring it down to 1 car - couldn't you drop off your daughter at school when you go to work? If she has to wait 30 minutes extra for school to start, as long as it's safe, too bad!! I had to do it when I was a kid! Sure, it was miserable waiting in the cold for 30 minutes, but boo hoo! Obviously depends on how old she is :) And once she's old enough, hubby and daughter could bike to school - just putting that suggestion up there. Then when you get home from work, your husband can take the car in the evening. Since he lives so close to home, any emergency that requires a car, he could come back home.
I'm sorry if I sound a bit harsh, but your debts seem a bit extravagant to decide to pile on more debt for another car. It sounds like although you're making progress to getting rid of your debt, you're still in the frame of mind that taking on debt for "stuff" that you need "right now" is a good thing to do.
Good luck with your debts and financial and personal goals, I hope that you achieve everything you set out to do. All the best :)
