I know there are many expensive classical guitars, but in most cases, they are not worth the price they are asking for them. $15,000 for a classical guitar which is made of wood and nothing really special or exorbitant expensive materials, such as diamonds and other rare expensive materials found in watches, bags, etc, is ridiculous.
I doubt this guitar costed more than $5000 to manufacture. Its huge profit for the luthier and whoever is selling them. You're mainly paying for the "exclusivity" of having an item that very few have. In other words, the luthier or manufacturer build their name up so much, that their instruments are overhyped and people who are willing to pay these prices, especially famous musicians, increase the "value" of the guitar.
So the original price was probably not $15.000 but now that is owned and used by a famous musician such as Ana Vidovic, they can get away with charging that much
I refuse to believe this guitar is 15k worth of materials
