Andy Cunningham (AndyCWB) has set up a rather fine website using the Wiki system, for all things Land Rover. There is plenty of Range Rover material already on there, but other areas need development.
http://www.landywiki.co.uk/The format really works well for expert information such as buyers' guides, frequently asked questions about different models, etc. So if you're fed up of retyping the same answers in web forums all the time, how about adding the info to the Landy Wiki?
I hope this develops into an excellent resource, it has great potential!
