Find out when the headgaskets were done. Not all replacement jobs used the updated gasket from what I've been told. I had mine done at 66,000 miles and now it is weeping coolant at 226,000 miles. Another well known item is the fan clutch at 200,000 miles. Count on going no where without snow tires if you get snow where you live. Look for water stains near the back windows. I go through a lot of steering dampeners - cheap item though.
