If you can wait the new Victory models will be released the last week of July. When the new models are released the older models will go on sale. If you prefer not to wait then use the pending release and inevitable sale as a bargaining chip to work in a discount. In this economy it never hurts to ask for a discount on any vehicle purchase; you won't be the first or last person that hasasked that dealer for one.
Thankfully you have a much desired HD model. SG's sell quickly if you are too aggressive with your pricing or aren't upside down on it.
The wind / buffeting issues are one of the most common XC complaints on the Victory websites. With all the submission that include height, weight, inseam and so on it makes it pretty easy to figure out which windshield and/or windshield and lowers wil work best for you. It's not exact science but most science isn't exact; there are too many opinions and tolerance levels to guaranty a perfect configuration.
Best of luck on your sale and future purchase! I'm sure your wife will love the XC; you'll probably be taking a lot more trips to Vegas!
