Help Mom Pay Her Loan

My Mom, Maria is a 53 years old woman who worked hard all her life. She always had two jobs at the same time to be able feed me and my brother. We didnt have much money, but we survived and got educated. Some years ago she bought a car by deviza loan. The fees were increasing as HUF value decreased. She had to give back the car to the bank because she wasn't able to pay it anymore. Despite she payed the price of the car, and she also gave it back, bank wants her to pay 10,000 euro (3million HUF) for a car she doesnt own anymore :( She cant get a third job, so I try to help her every way possible.
