Mobility scooter (SG12)

I am looking for a mobility scooter for my 95 year old father in law, he has a lung condition so I'm trying to get him his mobility back. He is fearcly independent so a scooter will give him back his mobility. We are trying to get him Attendance Allowance but it's a long process and as he is not well I'm unsure if he will be around if you have a scooter you do not use please contact me it would greatlfully be appreciated.
