See if it has a new radiator (neck break problem) or if the neck has been reinforced.
Check the mounts - also see if the engine fan is still centered, if it sits low, the mounts and/or subframe bushing(s) might be going.

I was quoted $800 for chain and rails....that was before the one rail pin wouldnt come out, and pass. side cam and lifters had to be replaced.

Drive it, and see how it "feels" ...relax, and let the car tell you wether it has liked its life so far or not.
