Dealers or salesmen are people and have different personalities. Painting all Kubota dealers with the same brush is approaching predjudice.
There are two dealers closeby in my area. One is a giant and is stiff, unyeilding, and used to selling million dollar tractors to huge farm co-ops. They have no interest in a little guy like me. They gave me a bottom line price that was quite good and said take it or leave it.
The other is a small mom-and-pop operation with a "feet up on desk" approach to selling tractors. Very pleasant to deal with. They beat the price of the big dealer with much consternation and a razor thin profit margin so they got my business.
However, had the big dealer had the best price they would have had a sale. We are not making friends here when it comes to the pocketbook. In fact, servicing will be done at the big dealer since they have a wealth of experience.
Salespeople try to establish a personal relationship to gain an advantage. Some of them may think that downgrading the competition is one way to achieve that since they are giving "inside information" of some sort. But you have to get past that. You have fallen victim to sales tactics whether or not they are pleasant from your point of view.
Ignore the periphreal garbage and only look at the bottom line - price and features, bang for the buck, or whatever you want to call it. You are the one in control.
Oh, and Kubota marks up their tractors by 20% to get MSRP. A dealer needs 7% to survive. That gives you 13% leeway to bargain a price.
