2006 Sportsman 450 Price

I recently bought a Jeep CJ7 and am looking to sell my 2006 Sportsman 450. I’ve looked up blue book to get a starting price on what to ask for it but I’ve run into a roadblock. They go by average condition and mileage which I’ve heard is anywhere between 800-1000k miles a year. My Polaris has spent it’s entire life in the garage on a battery tender and only had 56 hours on it and 492 miles. How much does that factor into the price?
