*Blue Book® Sug. Ret. Value = Kelley Blue Book® Suggested Retail Value. According to Kelley Blue Book®, this value represents the amount an auto dealer might ask for a specific vehicle. The retail value is not a trade-in or private party value. We check and update our used vehicle values often but these values may change slightly from one day to the next. At your request, Jerry Rome Nissan will gladly provide you with an up-to-the- minute suggested retail value for any of our vehicles.
