AIBU to ask my DD for a contribution to her car repair?

[wanteddeadoralive18]

DD (17) is doing her A levels and works 10 hours a week.( I am Single parent and work full time if that's relevent)
For her last bday, i paid for driving lessons and a car for her. DD saved to insure the car.
Car has just had some work done on it and we received a £200 bill for the work. As its coming towards Christmas, I have asked her for £100 towards the car bill and I will pay the rest - I am also having 2 new tyres on my car so already am paying out for that. When I asked her she was upset and complained that it will be 2 weeks wages - AIBU to have asked for the contribution as she has made me feel harsh??

Blimey. You bought her a car!! And she hasn’t even done her A levels? You clearly live in a different world to me.

Yes, but it's clearly one where a car is pretty essential, rural lives are quite different to urban ones, without a car is reliant on people to drive them around, and an A-Level student is able to choose to live somewhere else so they don't have the transport costs. So I'm sure the car wasn't simply an extravagant gift, reliable, efficient, fast transport makes a huge difference to some, for me as a city dweller the car sits idle most of the time, and nothing about my life would change if I couldn't afford it other than recreational things for me or the kids - things which would go anyway if money was tight.

As long as the family all knows the set up, then it's reasonable, and the DD seems happy so all is good, the kid giving up the car though would harm her mum I'm sure, either by having to run her kid about more, or likely her kid "staying with friends" all the time, and rapidly moving out, or perhaps just staying home depressed.
