Beauty Chris! Must dig out some pictures of my old 88 inch Series III, which I had for ten years, took to some impossible places, and wish I still had!!
But, to answer your question, yes. The Series III Land Rovers were replaced, in the early 80's, by two new versions, with coil springs all round, and various engine options, including the 3.5 V8. The 88 was replaced by the '90' (actually 93 inches), which became the 'Defender 90', and the long-wheel base 109 was replaced by the '110', later 'Defender 110'. This line is still current today, and can be identified by the wheel arch 'eyebrows', and a flat front, incorporating the radiator grille, one piece, wind - down windows in the doors, among other details. Extremely capable off-road vehicles - even US Special Forces use them.
