Big thanks to Neil for sorting out a retro-fit ISOFix for my wife’s Merc, its a more modern version that allows the fixing to swing out when needed.
Its a good value genuine piece of kit that arrived quickly and is an easy DIY fit, back set out, bolt & nut fixing, back seat in according to you tube

We now can borrow the Grandchildren for visits safe in the knowledge they are protected whilst travelling, cheers Neil
