Dear PJ,
besides a Genos, I have a Clavinova CVP309, at its time (2005) the top of the line, still very nice to play, with a beautiful polished ebony finishing.
To move it is obviously totally different than moving a Genos, or other keyboards. But not impossible. When I moved to the present new house it was transported without disassembling, together with our furniture, well protected with pads.
But it is possible to disassemble in two parts and load it in any station wagon or hatchback. The only problem is the huge weight of the upper part (all thick wood structure, hosting the big audio system also, the amplifier, ecc) that requires AT LEAST 2 strong persons to be handled.
For maintenance, no problem, since the Yamaha technician comes home for any repair. He did the complete replacement of the keyboards contacts, two years ago, at a reasonable price.
Although my Genos is connected to a pair of excellent Yamaha HS8 monitors, when I play the Clavinova the sound is amazing. And the piano sounds have something more.
The real problem ov the Clavinova is the price......
Ciao
Angelo
