My only suggestion is to take a good look to see if the bike was well maintained or abused.

You want to note that the calipers are centered faintly well, the rims don’t move radially or laterally a few mm’s when spun, chain isn’t all gunked up. If the bike looks like the last time it was cleaned or tuned up was 2014-2015, that might be the case.

Since it is an expensive bike, it should look clean and everything turn/shift smoothly. And… cables having end caps is a good sign.
