When I bought my Ace I went ahead and got the roof, half windshield, rear panel, winch switch that goes on the shifter, front and read brush guards right from the get go. I will purchase a winch elsewhere as I am not sold on Polaris winches and their pricing for them. I do however wish I would have purchased the over head trail bag and behind the seat trail bag. I am still contemplating the rear cargo box too, but there again after seeing one on another Ace today I am not completely sold on it, sure it looks cool but it's a little smaller than I thought it would be and only one side on it opens completely. Other than that I will be adding an aftermarket light bar,HID lights, tires and rims those are items that Polaris loses out to because of price point in my opinion. The nerf bars are pretty cool too another thing I am contemplating. The fender flares cover the stickers a little so I don't want to get those. The Polaris half doors and decals are cool as hell but way over priced. Just my thoughts and opinions hope this helps.
