I hope that they do keep at least a basic model going. Saw one today at my local garage that had jammed in diff lock (pilot error not disengaging on the road) that was classed as a tractor. Bloke runs it on red diesel on his farm, every panel dented including the roof, seats in tatters etc etc. Still looked the business at 25 years old with probably another 25 to go...
Still remember my first Range Rover in 1972 with two doors, rubber mats etc and the Chelsea tractors they've become at almost a £100,000 with pile carpets.
There'll always be a buyer for a Defender somewhere !
