Brown engine coolant
Discussion

Oil is way over 16psi where it passes through the head gasket though 
Smarty pants, its high pressure on one side of the system and a slight vacuum in the cylinder head drain channels that also pass through the head gasket Its probably rusty coolant though poor servicing, might cause a problem might not. If its cheap then buy it and get it flushed asap. Knock a bit off the price?

Could be major, could be minor. If it looks like tea/coffe without milk then I'd say it's probably not too bad.
Thick milky coffee/tea though and I'd be more concerned. I've flushed many an old french cooling system and only ever seen brown coolant. As said above it probably just means it's overdue a good flushing.
OTOH one I did took me about 30 minutes of flushing/reverse flushing water through the rad and had some serious thick gunk in there, like milky tea/coffee. Despite another 2 flushes in 6 months I never got it to stay clean and then the HG went at about 10 months.

You'll find another. I would be suspicious of completely clean coolant though. Perhaps they're covering something up.
do you have colour chart then so that people can choose wisely based on the exactly right colour that you think the coolant should be? is there a just off blue or red hue of coolant that to you would suggest its acceptable? LOL.You'll find another. I would be suspicious of completely clean coolant though. Perhaps they're covering something up.
never heard so much bunkham in my long life. if its clear coolant surely thats the very sort of sign you should be hoping to see? where do you draw the line on an engine that appears to have been well maintained - is it a case oooh....its looks well maintained but it must hiding something.
presumably on the same logic if you pull out a dipstick and find lovely clean engine oil and its at the correct level your alarm bells go off and you run a mile ......
