Many moons ago I was at Stoneleigh show ground and saw some guys from Land Rover driving a brand new stage 1 V8 SWB county SW, was red with limestone roof.
I have used my series 3 swb petrol landy for towing my twin axle car transporter with a car aboard many times, she handles and copes extraordinarily well no lack of power on inclines and the brakes stop you quickly and safely, NO issues at all. Kind regards. Chris
