Could be, but it's hard to tell. From the other scuttlebut 'round TBN it appears that Kioti (the company) has been trying to "weed out" the "fly by nighters." I don't know how effective they've been to date, but it seems like a good thing to me. Regarding determining if this dealer is a "fly by nighter" or not, I'd look at a few things.
1) How long has this dealer been in business? (1 yr, 5, 10, etc.)
2) What is the size of his maintenance facility (e.g. does he have a good mechanic's workshop, high supply of parts, etc.)
3) How long has he carried Kioti (~ 17 yrs is the max)
4) How many tractors does he have (e.g. more tractors = more inventory = more investment)
5) What other brands does he carry?
6) How long has he carried the 'other' brands.
7) Does he sell "other stuff" - e.g. used cars, boats, etc.
Of course, just because the fellow hasn't carried Kioti that long or doesn't have a lot of stuff on the lot, it doesn't necessarily follow that he will be "gone tomorrow." Same thing for being on the web - maybe he is an "old timer" or doesn't feel he needs the extra advertisement.
It's definitely "buyer beware", but by answering these questions (and others you might have thought up), it may point you either toward or away from this fellow.
