Phil is correct there, oates. You probably will end up paying MSRP plus tax and license, and as he said, haggle the price for the extras.
BUT, you'll find later after looking back at it, and AFTER you've contacted Brent(or any other reputable dealer of aftermarket parts for these machines) why you even bothered to sweat a few hundred bucks this way or that on your initial purchase agreement to begin with!!!
(am I right, fellas???!!!)
