I wouldn't get to worked up about it. After all, is it REALLY all that big of a deal? Did they do anything more than you yourself wouldn't have used it for? Yeah, I get it, they have plenty of other machines that they could have used. It was one guy in the service department 🙄, do you really think the owner told him to get out there and use "your" 1025 to plow the lot? If it really bothers you that much, just tell the salesman that you're dealing with about the incident, because that's the guy that this will matter the most to and who's livelihood depends on your happiness and return business. You can bet that he will mention it to the service department. As a side note, I actually had this happen to me. Back in the 80's, I bought a new Dodge Power Wagon with the Sno-
Fiter package. I found out they had been using the truck all season to plow their lot. I later found out (years later) they had damaged the tailgate and repaired & painted it.
