Tubaman,
I thought about answering your question as a dealer but I started to think about what I look for as a consumer. I can say that what I am looking for is value. I see value differently though than most people. I say that because I read the posts here and I think most people put value in the absolute lowest price. I put value in knowledgeable
on site service.
For example I am buying a new chain saw. Either a Jonsered or Husqvarna (I'm leaning toward the Jonsered 2165 but that is another discussion). Of course I could buy the Husqvarna at Lowe's or the like but I wouldn’t even think to look there. Sure they can get me parts and a great price. But I have better things to do than repair chainsaws or wait for my chainsaw to make its way through the UPS mailing bureaucracy going to and from the factory for repair. We wont even talk about the industry experts I will have to talk with to get the service in the first place.

I want to take it to a dealer if there is a problem, fill my coffee cup with some good "counter coffee", throw the saw on the bench and say "it is broke, fix, call when ready".
I want to find a dealer that I know wont screw me on the repair price, if he said it took two hours to fix I know for a fact it took two hours. And yes I expect it might break down, the trend seems to be that a warranty implies trouble free ownership. I think that it completely unrealistic, it is still a mechanical device built buy flawed humans. Also when I buy it I want somebody to set it up for me and test run it before I head up to the ranch 140 miles away.
So I guess if it was me I would look for on site repair, at least one mechanic that works full time and in a shop not just on the slab out back. Talk with the mechanic for 5 min if you have a chance does he sound like he found this job because his sisters ex husbands uncle couldn’t get him hired at burger king or does he sound like the guy the Montana rep might call to answer the hard questions. Ask what the service rate is after the warranty runs out. It might be 70 per hour, if it is, does the mechanic and shop look like your getting your monies worth? I would also go with my first impression of the dealer it is your best defense. The big dealer might be a super guy or a complete jerk. Same for the tin shed guy. My dads JD dealer for 30 years is now out of business so time in business and carrying major brand names can be misleading for predicting the future.
The margins on service and parts are 2 to 3 times that of sales. A mechanic sitting idle in the shop costs more then tractors sitting idle on the lot unsold. So buy tractors down the road all you want I would love to fix them.
Sorry this was so long
