Thanks for all the feedback guys. I've pretty much been set on a G8 for awhile now, and this pretty much solidifies it. Now I just need to find one in my area that has the options and color I want - they seem to be a bit rarer here in the Northwest (not counting the TWO GXP's in our area currently for sale - but logic tells me I should really go for the GT and with the savings I can buy an older Toyota pickup and get my wife granite countertops).
Buy a GXP plus a snow tire/wheel package. Your wife can wait on the countertops. F*** logic!
