The piano is perfect - I'm extremely happy with it. It looks brand new inside and out. I played it quite a lot (although I'm only a beginner) and I really like the tone.
Thanks very much! A friend of mine at work paid £3000 for a 1968 black U1 last year (after shopping around a lot), and so he was surprised that I only paid £2495 for a 1977 U3.
