Does anyone have any experience or ideas on buying a Monster from the Portland dealership, and thus avoiding the 10% sales tax in Washington? I know I'd be hit with excise taxes going back to Washington. Is there any way around this? Someone once told me that if you kept it unregistered for a year, then reigistered it, you save the tax $$. Not sure if this is true, and it certainly bends the law, but has anyone done this?
