Welcome. The 4340 is a great model. I go back and forth on this but I really honestly belive that the 4340 open station is my favorite. This tractor is a work horse with large open deck.
There is every reason to look at this tractor in my opinion. All the standard features, the quality of build, the value etc.
It has a lot to offer and is very, very strong with lots of standard features. I love the Mitsu engine and have only excellent things to say about it.
As far as price it is really quit a different story from region to region. It was brought up in another thread and in a different brand but the poster said it pretty well.
Many factors come into play. The cost of doing business as a dealer varies, has insurances, employees, cost of various over head in the region, shipping, does the dealer offer excellent customer service ie. if warranty issue pick it up and return it free. This with the crazy cost of fuel is coming less and less I think.
There are many factors coming into play and the dealer has to make a fair margin to be able to operate and be there for you in the years to come. Being a dealer of trucks I am sure you are very aware of this at least more so than many people.
So, I can't really say what your area will bring in a price but I would talk to the dealer and see what you think of him and what he has to offer, drive the tractor (you will be impressed) and go from there.
I wish I could be a bit better help in this area. Once you drive it let us know of any questions you may have and I will certainly do my best to help out.
Best of luck,
