This is my second Murano SL. I live in a flat area with mostly 50/45mph speed limits. I average 24.4 mpg without driving like an old fogey. I get the same or better on the hiway. I have experimented, and the car runs fine on regular gas. No difference using midgrade or premium gas.
Backup camera, Satellite radio, leather seats with heaters, lots of baggage and passenger room. Good power, smooth ride.
Better tires - My Goodyears are noisy. Can't wait to replace them. Cruise light is too bright (covered it with film). Can do well without keyless system. Don't lose your fob big $$$$$$!
