Where have the external hinges gone?
Into the bin marked '20th Century' where they belong? The internal ones won't rust.
It looks to me like the new Defender has been designed to be a practical, capable car for people who need such things, usually because they work in the countryside. Instead we get whinging from 'enthusiasts' who don't live in the country but want an archaic novelty that they can stick the contents of 4x4 monthly to.
The only reason the old Defender stuck around so long was the military market, but now even they want something more modern.
