Looks amazing, good luck on your sale.
I'm a big fan of Yokomo and have a large collection of Dogfighters, I think I have around 7+ YZ870C;s (1 NIB, One New built - Pristine, 1 in amazing original condition (my original YZ870C I bought new in 1988 and raced), 2 in average condition and 2 that need proper restoration).
I also have 2 ZY10's (carbon chassis etc) which are in great condition but need a little TLC to be amazing shelf queens.
