We really need to get some money back on this power wheelchair adaptation but I thought I'd show it here before putting it on E-bay. Maybe someone you know might need it. No reasonable offer refused.
The cost of this adaptation was (and still is) around £4000. The wheelchair is a separate item that has to be bought first (around a £1000). The seat size is 16" x 16".
Although this item is some years old, it is in good working order, having had new batteries during its lifetime. It would have to be buyer collect only unfortunately. PM if interested.
The wheels are also detachable for even flatter storage/transportation.
