Many thanks for the info. This I aready have, but I thought there is one with deeper insights!
Its about on a par with handbooks from other manufacturers that tell you how to programme the sat nav, top up the oil & washer fluid. Everything else is refer to your dealer. My 1980 Range Rover book has 60 pages on routine maintenance plus other sections on lights, wheels & a circuit diagram. Its a vehicle you can open the bonnet & identify actual components not plastic covers.
