E bodies should not rattle when the doors close unless the channels or something else is worn out. I restored mine some 25 years ago and it is a great car to look at, but the driving experience leaves a lot to be desired, unless you just like going fast in straight lines. With the 440 up front, it is too front heavy and handles accordingly and the ride is pretty stiff with the stock springs and the seats are not that well contoured for an enjoyable drive. But it is fast and everyone that looks at it drools. I am considering letting mine go to a good friend that really wants it bad so I can spend more time with my C bodies. He is relatively young and I am older and wiser now - well maybe just a little.
