I need some advice regarding step daughter 20 has a good well paid job, own home her and her boyfriend have good salary jobs, car has broken yet again, they asked us to pay last time and was told no, partner and I have own cars but low income due to disability, but add not disability vehicles, one of us work other doesn't so low income, they go on trips, holidays and enjoy spending and we have tried to instruct them to save, but to no avail, as one of us doesn't work we can get away with one vehicle and as such other has been loaned to step daughter for afew weeks whilst cars been at garage, it's booked in to be fixed but it's now looking very much like something bigger is going on and it's gonna cost alot, possibly more than car is worth so maybe going to have to get rid very old car, told partner the car was loaned for a set period of time and now I want car returning to myself as I'm missing my freedom and been able to have use of the car I'm effective paying tax insurance and mot on, yet today step daughter has stated when I asked for it back on x date (30 day insurance runs out) that I carnt have it back if their current car cannot be fixed or needs to go off road, no asking no can I just well no you cannot collect said car and keys if I haven't got my car back, I'm not in a position to be able to give/buy another vehicle for them, I've given them opportunity to sort something out and without sounding harsh it simply isn't my problem, unfortunately they live to far away to be able to give lifts, obviously if hospital appointment or food shopping I'd help out no kids involved and boyf can walk to work, it's ten min drive for her commute but a taxi is possible, am I been mean asking /taking my car back, if car ends up off road could really turn into months and I don't want them to use it, it's not a high value vehicle but it's mine, it allows me my freedom and I value it enormously
