I have driven large SUVs for the past 6 years, Ford Expedition and Chevy Tahoe. The Murano has a smother trans. and a very fun suspension. The stereo needs an mp3 jack and a bit better speakers. I'd also like to have heated seats as well. Electric leather seats are comfortable and very user friendly. I like the addition of the pedals that come forward. Gas mileage (avg 22 mpg) is a bit lower than expected, but much better than the large SUVs. AWD is great. There is a rattling sound that should not be heard on a new vehicle - one that the dealer could not find. Also, the 3.5l engine pings a lot even with super unleaded gas.
Fully adjustable seats, AWD, wide wheel base, "S" power to pass, fold down seats, moon roof.
Get rid of the tape cassette option in the dash and make the stereo dash board smaller and add more audio technology. Put an AC jack in front of the shifter rather than in the arm rest compartment. Maybe a bit more torque. Make an engine model that does not "ping" when using regular unleaded gas.
