No different taxes are built in (they are added on afterwards). However, there are different build configurations, ie different items are included in the standard equipment, and the packages have different consists. When you finish making those adjustments, the prices are closer, but we still pay a premium. That has to do with a smaller market, higher transportation costs, lower population density, resultant higher costs of distribution, etc. It isn't just true with BMW, the same situation exists with a lot of distributors of similar products.
