Bought it from qt a couple of years ago 56pounds + vat, guess it is worth about half that.  I am near Coventry so it would need posting.
Devon 4x4 : Off-Road Forum – Vehicle Prep

Tip:

On the inside of the 4x4 you will notice either an extra gear lever or dial on the dash which allows you to shift the vehicle into high or low range 4WD. As a general rule, for moderate inclines, slippery or sandy situations, use 4WD high range. For very deep water crossings, steep or rocky ground use 4WD low range. If you are not sure about this read your owners manual or join a club.
