Does anyone know if this will work? We have the newer model town car. It has a decent size trunk. I'm thinking of putting both bases of the scooter in the trunk and the two batteries (batteries don't have to stay on the scooter). Then, the chair part I'll put in the back seat.
You should have no problem the way you are thinking.
They should fit just fine. I know that when we had out Town Car, my full scooter fit in the trunk with room to spare.
When I had a Ford Taurus I was able to put my standard size ECV and Judy's Go-Go in the car. The seats went on the back seat and the batteries on the flor; we were able to fit everything else in the trunk.
