I have bought local and long distance for both well used and new, used I have absolutely no problem buying long distance;
I know that any maintenance and repair is my dollar and time, the dealers are a information and parts source.
New with a warranty;
I will certainly try and stay local because if I'm looking for warranty repair and am expecting anything more then the minimum from the dealer, such as extra parts while your in there, loaners or reduced rentals, extra effort to have something covered by warranty, maybe getting pushed ahead on other non-critical work to speed up down time, if I didn't purchase from that dealer should I expect to receive any value added service? If you don't support local dealers how are they going to stay in business? When they go out where is your service coming from?
So to each your own but if you buy new from long distance don't bit*ch when your local dealer treats you as you treated him.
