OP,
Wheels appear to match so unless the front wheel is out of whack perhaps no front end damage... where are the numbers for the auction at now, what would you be comfortable paying if there was slight damage? Not sure that there is a hole in the stay either.
One last thing you could drive out and have a look and if all is fine place your bid just before it closes and drive home with the bike...I assume you would have to pick it up anyway.
The only way to tell for certain is to have a look.
Best, Ben
