First of all I would like to have a short explaination off why vintage guitars are so much more expencive, and why people are saying they are so much better than the re-issued ones. Thanks!

Also, I saw this Vintage Fender Mustang 1969 on eBay, and wondered how much it was worth bidding on it.

It's not in perfect shape as you can see, but from what he tells, everything works as it should.
Thanks in advance!
