I've raised £8000 to Fund a reliable accessible car for Jenna’s wheelchair, so as a family we can go out together and enjoy life, without struggling continuously

Jenna is 26 and returning from university this week. Since the age of 3 she has had arthritis, this affects her whole body. Jenna gets around in an electric wheelchair, is constantly in pain, this however does not deter her from doing exciting things.
Returning home we have arranged the bedroom for living, she now has a shower room for her needs. The only thing now is that to get around Jenna has to be transferred into a car using a board and is then only able to take the manual wheelchair, which then reduces her independence when at a location.
What would life easier, a vehicle that Jenna's electric chair could be driven into. Strapped in and off anywhere with the family for exciting adventures. It currently is so difficult to do this.
I will selling my current car to fund this, however this will not be enough to fund an adaptable car. Huge care cost bills impact on being able to fund a vehicle in any other way.
Any help would be amazing to make a small difference for family treasured memories, which many find easier to do.
