100% possible. Quarrying company I used to work for had more buying power than dealers. Their price from Cat direct was less than the dealers could get in many cases. Almost certainly plenty of agreements in that case to not flip them right back to the dealer/other users.
its been a while since the conversation, but i want to say there was a timeline in which they had to possess the vehicles per their agreement. so if the mileage got racked up quickly they would park them.
