I'm looking to purchase a white SUV from Nissan. I'm particularly interested in a model known for its reliability and performance. Could you provide me with detailed information about the vehicle's specifications, including engine options, fuel efficiency, and safety features? Additionally, I'd like to know the pricing details and any available promotions or discounts. If you have photos or a brochure, please send those as well. I'm eager to gather all necessary info to make a decision soon. Thank you!
