I think it depends alot on whether or not you plan to do your own maintenance or repair work and how much you'll have to rely on the local dealer if you buy from someone else. I do all my own work so the only advantage to having a local dealer is getting parts (and my closest dealer is an hour away).
The local dealer wasn't helpful when I was looking for a used TLB. He started out by telling me that wasn't what I wanted, and that I should buy a
B3030 and add a loader and backhoe instead. (Of course, he had a new
B3030 he wanted to move).
When I told him I was really looking for a TLB like a
B21 (couldn't afford a
B26), he went on to tell me how I didn't need one, I had no legitimate use for one since I wasn't a contractor, hydraulics worked too fast for a homeowner to get used to, overkill for anyone other than a business, etc., then when I wouldn't agree with him he switched tactics and tried to sell me a new
B26.
When I explained I couldn't afford a
B26 (I had set a budget and didn't want to exceed it), he tried to convince me that the total price wasn't really important, as long as I could make the monthly payments. Wouldn't even tell me what the total cost for the
B26 was, just kept telling me the monthly payment amount. Finally after much discussion he tells me the cost, and I laugh since it is $12,000 more than what I told him I was willing to spend. Needless to say I hung up and kept looking.
I ended up finding a dealer in the US selling a demo
B26 with 25 hours on it at an awesome price. By the time the deal was finalized, I ended up buying a set of filters for the 50 hour service, a Kubota service manual, bolt on cutting edge for the front bucket, hydraulic thumb for the backhoe, and a block heater and horn kit. When I picked it up he gave me and my buddy some Kubota hats, an extra spare key, and a few pens.
Even after calculating the exchange rate (I live in Canada), I figure I saved $14,000 (yes, 3 zeros) over a new similar machine from the local dealer. Even though it was a 14 hour drive each way to pick it up, I am much further ahead and bascially have a new machine, at a price I was willing to pay.
The job of the salesman/dealer should be to help you find what you want, not to simply push what they have with no regards for whether or not it meets your needs. If they don't have what you want, they should at least have the foresight to try to create a relationship with you so you will come back for any future attachment or accessories. The arrogance and stupidity of my local dealer in trying to tell me I didn't know what I wanted just served to ensure I will NEVER buy anything from them other than parts and oil (and if I can buy from another dealer instead, I will). Their loss!
