I have guitars that are ten years old and have no noticeable blemishes. I'm really, really careful with them. No clothes with zips, presstuds, metal buttons, rivets, buckles or badges etc when I go to play one of my guitars and they live in their cases when I'm not using them to prevent accidental damage. I don't gig so nothing leaves the house. My brand new LP actually has more damage than any other guitar I own, so to say that they get dinged up anyway isn't (touch wood) true in my case.
I was going to be a pickguard off kinda guy but now feel forced to keep it on and even then it's bugging me that I know there's an imperfection underneath. Also, I'm of the opinion that a brand new premium item should arrive in mint condition whether it's to get bashed up during my ownership or not...
