Input: About a year ago my uncle gave my mum a car. She couldn’t afford it and asked me if I wanted it. I said yes and she said it would cost me £100. I thought she was being greedy asking for £100 for a car she got free but it was still worth it. Fast forward a year and the car is starting to have problems, I had to spend £180 to get a new part. So I told my mum and sister that I might not be able to afford to keep my car. My sister offered to buy it for £150, she was going to offer more but my mum told her she couldn’t spend more than that on the car. I thought she thought that the car wasn’t worth any more so I decided to get it valued by a company, they said they might be able to buy it for £400-£900. It would depend on an inspection and test drive. So I booked it in. 
I told my sister about the valuation and then I got a text from my mum telling me I couldn’t sell the car, it wasn’t mine to sell. She told me that it was only a loaner and I had to give it back if I didn’t want it. I asked her why she sold it to me then and she said she hadn’t the £100 was for transporting the car from my uncles 60 miles away. 
If I sold the car now my mum would never talk to me again.
I’m not sure what to do next, AITA.
