Does any body know why my car could be overheating, the temperature gauge needle goes up high and then goes back down. The water in the Radiator is a dark brown color and is thick.

Could be a number of things. Go see your local radiator specialist.

The temperature going up then down means you have air in the cooling system. That could be a minor issue or a symptom of a major problem. The dark brown colour is rust obviously which is not good. You say it's thick, it might be oil mixed in with it, which leans towards the major problem mentioned above. Best get it checked out by a mechanic, at the very least there is some urgent maintenance needed.

BMWs are prone to coooling woes if the cooling system isn't kept well-maintained [he says as a 5 times BMW owner.]. This doesn't bode well

Use chemweld and flog it off! Jk :P But seriously, it might be cheaper to find another engine, just make sure the cooling system is up to scratch.
50K without servicing! The man's an idiot! Sorry, but he is.

Take head off & take it to reconditioners to testif straight & hardness ,often just a skim & new gaskets & goodfor another 100 k . I had 1 that was warpedyet they managed to straighten it, cost to complete recon the head( inc valves )was $600 Wrecker wanted $500 for used 1 without awarranty .so could be just as bad . They did have a habit of headproblems if not maintained well .

You don't say what year it is but I'm assuming it's an E32! At any rate the V8 E32's and E38's have well documented problems with cooling fan/head gasket problems. My advice would be; get rid of it! Trade it in on a E39, 5-series 3.0 litre 6 cylinder.
