I have had a Yashica T4 for almost 20 years. For the longest time it lived in my car and much of that was spent on the dash. Every corner I went around the camera would slide from one side to the other. It eventually was so scratched up I couldn't see throughout the viewfinder but a little plastic polish cleaned it up. I lent it to a friend of mine for a trip to Thailand and she spilled bug spray on it. Melted the plastic all over the body. Dang thing still works, but it sure is ugly.
The only camera I ever ruined was a Nikon F2. Dropped it less than a foot onto a studio floor and the resulting tiny fall crushed the corner and jammed the camera. So much for indestructible.
