I like the ISOFIX system and had it in the UK, it's not approved in Australia so had to sell our seat etc. in the UK and buy new here. I believe this was in part to protect the local car market. The car we brought on landing had ISOFIX installed...but not allowed to be used. Aghhh.
However in a Morgan with the higher back seats is this a "tick box" exercise that will never be used?
