I use a AutoChair 80Kg hoist in a large car so not much help to you, sorry, however on the Autochair and Brig Ayd sites they list many small cars that can have a hoist fitted but one thing to lookout for is the size of your scooter and will that fit regardless of the hoist.
Size of scooter won’t be so much of a problem with the back seats folded or if you have one of the folding types but another area to lookout for is the height of the rear door aperture.
Only people to give a real accurate account of what will work with any given hoist and any given scooter is the Motability adaption installers. Motability have a list of them on their site and a phone call to one near you could help you out if you get stuck and overall I’ve found the installers to be more helpful than car dealers.
