Isn't it useless to tune it tho, if the buyer is going to drive it and move it anyway? Doesn't that detune it again?
There is no greater turnoff to a potential buyer than an out of tune piano. Especially if they came all the way to your house/apartment to see it.
Also, what felt do you believe needs to be replaced?
The serial number 157619 places it around 1971-1973.
I second this. If your piano is not in tune, a potential buyer will wonder how it really sounds, whether it can be properly tuned etc. And of course, you want your piano to sound its best when someone comes to play it, so that they will *want* to buy it.
In terms of the price, I also don't know much about the market for used pianos in Europe. But in the US, that price would be "ok" only if the piano was in good shape and could hold a tuning. Although, even then the price still might be a little high given that the piano is about 50 years old. have you looked at other people who are selling their pianos to see what kinds of prices they list? Also, you might compare your price to the price for a similarly age piano as sold by a piano dealer, and maybe think that your price should be maybe 30% less (since no warranty, no delivery). Maybe??
BTW your Petrof is very pretty! I'm biased of course because I owned a Petrof very similar to that, although it was made in 1989-1990. I loved that upright, it had a wonderful tone.
