I bought a $300 cover from some fancy custom cover maker and it sucked. I returned it and bought the Nissan-made cover. It works great. Get it from yournissanparts.com, enter "thenewx" upon checkout and get your cover at a discount.
Thanks for the response. I live near the ocean and the sea gulls did their mating dances all over the car I traded in for the Xterra. I actually witnessed it happen. They really scratched the hell out of my paint. Also they would peck at bugs and they made little dents on the hood of my car. Seagulls suck.
