11K a year in a Series Landrover? Hell in 1981 I had a Series 2A with a 4203 Perkins in 1981, 11 miles was enough. It was a Nuffield tractor with a roof, numb steering, suspension, and every thing I take for granted now, heater, wipers, insulation, brakes, non leaking, etc was useless. But it would pull a house down and cruise at 60 with high ratio diffs. You're a brave man!
