Wanna buy my car back

My name is sara , a while ago my dog ricky was sick and needed surgery urgently and since i didn't have money and the surgery was urgent i sold my car to pay for it. I have a lot of memories with my car and yes it's not that good but it means a lot to me, my dog and mate is doing great now thank god so i would really love to buy my car back , it will mean so much to me. Thank you
