I am considering buying a 1996 SC 300. During my inspection I noticed when I closed the door the moon roof moved up and down slightly. With the moon roof closed completly I can push down on it about 1/4 to 3/8 of an inch and then it returns back to the full up position. While driving I did not notice any unusual wind noise and the is no evidence of water leaks. I was wondering if this is normal?????
