Mobility Scooter advice. Please

[kPATm]

Hello all. So my Mother In Law has decided she wants a Mobility Scooter as she is basically been house bound for a few years. She needs something pretty small and easy to manoeuvre and that can be disassembled for putting in the back of a car. The scooter wont be used locally as the local area is very hilly. It will be used when she want to go on family days out really. Her budget is about £500/600. I know less than nothing about these so any help would be greatly appreciated. Thanks
