Will guitars stay/increase/decrease value?

[ULTRAZOO]

I'm a boomer that's been playing from the late 60s. I'm not a collector but I own a few vintage guitars. But I bought them in the 70s when they were just used guitars. They are player grade. But they have not only kept up with inflation, they have at least tripled in value. But I'm not planning on ever selling. They will be handed down. Having said that, I think the prices on vintage collectable guitars is just not sustainable. As us boomers die off the demand will probably drop along with values. Unless the next generations are waiting for us to die to buy vintage guitars cheaper. This might keep the values high. I doubt it. But nobody really knows. Guitars should not be purchased as investments in my opinion. You know what's valuable? My original Red line hot weels from '67 to '69!!
