Like Dwight, I was suggesting there is more to becoming a happy Triumph owner than getting the lowest price. Unlike auto dealers, where the majority of a particualr marque will do a decent job, there seems to be a fairly large group of lousy Triumph dealerships out there. Of course, I'm not suggesting a dealer that offers good service has the right to be dishonest but I'm not sure I'd call additional charges dishonest either.
If you go for the dealer that gives you a low-ball price, be prepared to do your own service work (it's not that hard).
