Ok, I'll toss my $02 in here. I don't blame a dealer for getting as much as he can out of anything he sells. Isn't that what this country is all about? Supply and demand drives the market. $4,000 over list? I'd feel free to shop elsewhere. Whenever I, as a buyer, decide to purchase a Harley, or any other item, I look at several things besides the cheapest price. Where am I going to have the bike serviced? Although I'm not above buying at one dealership and getting service at another, I'm not proud of it, and I try to remain loyal to one dealership. I expect that dealership's loyalty in return.
I'm in a situation now. I bought my bike from one dealer, but having it Dyno'ed and tuned at another dealer. They seem to welcome the business as it's generally slow in the winter. I'd find it very hard to go to this dealer who's doing the tuning and "Demand" anything. I will say that I will have to strongly consider the "Tuning" dealer the next time I trade motorcycles.
To earn my business, a dealer needs to be competetive, friendly, and offer service after the sale. In return, I will give that dealer first and last shot before I just trade elesewhere. I wouldn't move to a different dealer for $500 or even $1,000 on a $35,000 motorcycle.
