Well I'm back from helping out yesterday as a time-keeper for the Pyengana Endurance Race... only to find this discussion on Salesman/Dealerships.
Anyway, I've posted many times on finding out the reputation of your local area dealerships and using that as a factor in choosing your tractor. Circumstances of course play a part but if the salesman doesn't 'know' tractors, then I'd say you find one who does. Tractors, by and large, work & last a heck of a lot longer than a car or ute = you're going to be dealing with your dealership for a relatively long period of years (parts/service/advice).
I mentioned 'circumstances'. In my case, I live on an island State with an overall population of just under 520,000; just over half of which live rural. Which means, outside of the "Big Smoke Townies" (laughingly but true) you pretty much get know each other or of each other. That also means that "word travels fast", so a tractor dealership's reputation will make or break them. Being such a rural State you'd think that we'd be inundated with TV advertising from the various tractor/implement colours, but the opposite is true. Also, living on an island means we've got a huge moat around us; which means shipping/transport/distance costs = yes you can buy a used (previously loved?

) tractor from the mainland, but you've still got to get it here. There are no multiple coloured dealerships here: 1 JD (3 branches), 1 CASE IH, etc...
I happen to know that all of my Tasmanian JD salesmen are farmers or semi-retired farmers themselves. It's part of their reputation here. [I can't speak to the other dealerships as I've not dealt with them, but they'd be fools if it wasn't the same]
When I went (2 hr drive) to visit the JD dealership, I brought a long-time local Mate with me [Note: he owns an old small YANMAR]. Turned out that they (Mate and salesman) had quite a few acquaintances, but other than that my Mate just sat quietly by while the salesman & I talked. He asked
a lot of questions about what I was going to use my tractor for... the hp kept climbing, along with the price!
Short story is that the salesman could have sold me a 45hp tractor and I would've been none the wiser. Instead he sold me a less expensive (41hp) tractor that fitted my needs. Yes, I signed the order chit... no money down (I was paying cash) until the tractor & implements were delivered to me,
and a handshake. Done.
Maybe I live in a land that time forgot, but it's the way things are done here.
