I have a '97 1.8tq with 95k miles. In my coolant resevoir there is thick brown gunk. It is like a thick chocolate milk shake in there! What in the world is going on?

The shop may suggest a bad head gasket, which would probably hold true on most cars. I would insist they replace the oil cooler first, and see how that works out. That's generally what fails and causes this on these cars.
Cost...not really sure. I'd say 1/2 hr to replace the oil cooler, oil and filter change, the cost of the cooler, and probably 2-3 hours to flush (several times) and fill the cooling system. That oil/coolant sludge is tough to clean out of the cooling system.
