Like I said on FB, look at the front and back of the engine to see if the LIMG or HG are leaking externally. Check for what looks like coolant blow out of the overflow tube on the coolant bottle, which would point to combustion gasses being pushed into the coolant system (I drove my Alero like this for 6 months, including a trip from Philadelphia to Lansing (700 miles one way))

Also check the oil for mixing of coolant and oil (very bad thing)

They are really the only MAJOR issues I can think of. Everything else comes down to care (tires, rubber lines and hoses, suspension, etc)
