Remember you are buying a Land Rover not a "car"
I purchase a 1971 Serie IIA X-MOD from a well knowed Vehicle/parts shop in Vermont U.S.A. for 10,000 US$ some 2 years ago and a 1995 Disco from a local fellow here in Montreal, Quebec, Canada for 7,000 CAN$ with 165,000 Kilometer on the dial. In both cases I was and still very happy I purchased them.
Of course I ad to invest some time and pesos for repairs and ajustments, nothing to make me a poor man.
First: Try the vehicle, fully open windows near a wall. If you ear squeek, cronk, etc. investigate.
Second: With all the windows closed, no radio, listen, any noise, investigate.
Third: Look all over, oil spill, excess of oil or grease on the fire wall, under the oil pan, oily spot on transfer case, differential.
Fourth: ask question, get answer.
If you are satisfy, buy.
Then stay away from any dealers if you do not want to spend your paycheck on your new baby.
Keep seeking information by reading pass posting on this forum, if you do not see your answer then ask. Read any Land Rover related literature and magazines. Try to do as much as possible by yourself "mechanic wise" the rest ask around for the best mechanic shop that knows about Landy.
Remember they are special vehicle because they need tender loving CARE.
Good luck :clap:
