We are trying to sell a second hand Stannah 229 (right hand fix - two bends) stairlift. Any ideas.?

Second hand Stannah 229 stairlift in pearl body colour and peach upholstery. The unit is currently fitted into an exiting stairwell on a dog leg stair with half space landing. The right hand mounted continuous stairlift is in four sections which can be unbolted. The unit comprises powered lower rail which can be raised when not in use, manual tilting footrest, right hand controls, lap strap, powered swivel seat and power unit. The chair lift was bought new about eight years ago and the approx dimensions are lower flight (6 treads), total rise 1140mm, total going 1170mm, 1760mm x 920mm half space landing, second flight (7 treads), total rise 1290mm, total going 1390mm. This unit proved invaluable to my mother in law who suffered from severe rheumatoid arthritis.
