I haven't looked up what the law says, but I can pass on a related experience I had. I bought my
BX2200 with FEL, MMM, grass blower, & grass catcher from a dealer 50 mi. away as he was $3000 lower than my local dealer. About 9 mos. later Kubota mailed out a written recall on the fuel tank. I called my local dealer's service dept., where the svc. mgr. told me that they wouldn't do it. I called Kubota's U.S. headquarters and was told that all Kubota dealers, in order to qualify for dealership rights, have to sign a contract with Kubota saying that they provide warranty work to any customer, regardless of where the tractor was purchased. I was told that dealers can even have dealership rights revoked for refusing to comply. They also told me that because it was a recall, I could even require the technician to come to my location. I then called the local Kubota svc. mgr. back & related what I'd been told. The guy gave me an angry lecture about losing money because of the small amount Kubota pays them, both on the repair and the travel time/gas, etc. He was sort of a grouchy ole guy to start with; I suppose he was also angry that I'd dared call Kubota and then present to him information contradictory to what he'd told me previously. In the end, he had to do it. He procrastinated a few weeks (I'm sure I was put at the bottom of the list & kept there until their schedule hit a slow spot), but it finally got done.
I suppose I could have filed a complaint with Kubota re. the type response I got from the local svc. mgr., but I figured once the warranty is expired, I have to negotiate with this guy on my own, so I didn't. Too bad some of them are this way. I'd guess that some tractors sold by my local dealer end up far away needing svc. elsewhere in just the opposite situation, so it would seem that it all comes out in the wash. Maybe the sales and service departments in some places operate pretty independently of each other and maybe each has to show a certain bottom line profit to the owner. This is just a guess. Seems like they'd realize that courteous svc. would attract loyal customers.
You might give thought to these issues: If this was your local dealer, was he trying to bluff you into buying from him rather than someone else because he has a higher price? If he was lying about this (I'd think apparently he was-or on the other hand maybe he doesn't know his facts correctly-that'd tell you something about him too), will he also be dishonest re. other things if you do buy from him. You might possibly call Kubota U.S. headquarters & ask re. their current contract policy. Then, depending on how you feel this'd work, go back to the guy & see how he reacts when you relate what they told you (He migh back off, or he migh blow up; either way you might get some insight to the guy's character.) Is there another dealer not too far away who can provide service/maintenance for you? Good luck with your decision.
