IMHO
...the best dealerships of any product tend to be sole distributors, or at least limited distributors. When you are carrying multiple products, you can afford to let slide on one or two; when you're only pushing two or three, you push a little harder.
Unfortunately, apart from Harley - who are smart to have sole distributors - the majority of motorcycle dealers seem to have to sell and support multiple brands, which dilutes the passion. Although we may not be great Harley fans, they have a great marketing strategy.
Siggy
