Help me keep my partner's car

In January 2015 I was lucky enough to meet my partner Jessica, sadly after two loving years together, she passed away on the 17th of January this year.

Her dad is saying she owed him £4k, so he wants to take the car we both used, to recoup his costs. Me and Jessica made our memories with our car, we used it to go everywhere together, I don't want to lose it. Please help me fundraise the money to be able to pay him, so that I can keep our car.
