Okay, I am going to be the Grinch.
Kevin Mahoney is the owner of Classic Motorworks, which hosts this forum. I, for one, find it in poor taste to use this forum with the intention to bypass the importer who supports it. A lot of information is freely traded here, but I think this steps over the line. As a dealer I find the price or parts and accessories from CMW to be at or below industry averages. Part of the costs associated with the parts are import duties. ARE YOU GOING TO DECLARE THESE PARTS TO CUSTOMS AND PAY THESE TARIFFS? If so, you will find the pricing much closer to local pricing. Also, you will find that the parts you get will be generally sub-standard. Kevin brings in the best quality available for export. The stuff that is not exported is not made to the same standards.
That dealer you don't want to buy parts from has a labor rate predicated on selling those parts. With no profit margin from parts labor costs you more. Your effort to "save" will cost you more in the long run, plus a higher percentage of the money you spend will go out of the country.
We all want to save money. You are trading short term savings for long term satisfaction and usage. And you are doing this in the forum of the very people that make it possible for you to get the product. At the very least, you might consider taking this discussion to one of the other independent RE forums.
