Having read the thread, I am not exactly sure what you are looking for, and I am not sure if you are either.
A few general points from someone who has bought, and sold, more Series than I can count over the years, the last one being a 2a in June this year.
For a start, I would ignore ebay, and dealers, altogether. Ebay is a well known source of stolen Land Rovers, bitsas, and trouble of other kinds.
Dealers always want to make a profit, and usually do this by concentrating on improving the cosmetic appearance of a vehicle, without worrying too much about originality or mechanics.
Also, I get the impression that you haven't owned or driven Land Rovers much before. So familiarise yourself with the subject by reading up on the history of the different vehicles, what the different variants did, and what was fitted to them.
And look at plenty of vehicles, both online, and in person. Test drive as many as you can, so you get a feel of what they should drive and sound like.
For starters, have a look at these. I have already filtered out the dealers, they are all private sales. There is a wide variety of prices and conditions. Ignore the one that is obviously a One Ten. Best of luck.

Thanks for the advice, I was trying to take all ebay/online ones with a pinch of salt as the sellers can make the pics say what they want it to. I think having read this thread I can see that over the 50 years a land rovers been around it can really become so many cars all at once. forsalelro does honestly seem like the best site I've come across so far, been looking daily for something to come up that seems like it'll work out!
