I upgraded from '03 to the '09 and am loving the improvements that they made. The new Murano has a very high class feel to it, with the plush leather seats, ambient lighting, and all the other features I loved on my '03. I got the Premium Package, Technology Package and Leather Package on my SL. The Bose sound is amazing. The leg room in the back seat is still unbeatable. My 6'8" friend has said he had never been able to ride comfortably in a back seat before riding in my Murano. The intellikey system is too cool. It has bluetooth capabilities, built in XM radio, power lift gate, xenon headlights, and so many more awesome features.
I love not having to dig through my purse to find my keys. The Intellikey system is awesome. I can unlock the vehicle, jump in and start it without having to try to find my keys. I also love the ambient lighting throughout the interior, it really adds to the luxury feel of the vehicle.
