Five years old is classed as 'vintage' for a lot of eBay sellers!

I suppose the older you are, the term 'vintage' gets applied to older and older instruments, whilst to younger people, a 20-year old guitar may well appear vintage.

I know that a true 'vintage' guitar to me would mean something pre-mid '60s, but to many, it may be pre-'80s or even pre-90s.

In the end, they are all just used instruments of varying quality.
