Is it a known brand/company?

Also why do you want a 20000 grand piano? Is it a show piece for the house? Is someone at the house a concert pianist?

My inlaws bought a huge expensive grand piano and then had to protect it from all the little kids and they didn't keep it very long. And no one wanted to sit around and sing and play with that piano. It was too much.

My piano teacher had a grand piano that we would play only for recitals and shed play it sometimes but mainly we used a different piano.

I would get a nice used upright and dump the old piano unless its an investment piece that will be worth 20000 after you fix it up. Do you have a piano store around or post on some piano sites to ask?

Unless your a concert pianist or need a show piece for the house why spend 20000 on a piano?
