My daughter bought a Mokka X Elite on the 7th August, after six days the engines management light came on. She contacted the garage who after a discussion agreed to pick up the car. After seven days she called to be informed they could not find any issue and the car had lost its data. Since the this has occurred three times.

Yesterday she called the garage to be told take the car to them. Sorry no courtesy car until January. I don't trust the garage but she love the car. Can she return the car and demand her money to be returned minus say £500 for millage covered?
