2006 Nissan Altima 3.5 SE 4dr Sedan (3.5L 6cyl 5A)
I drive mainly in city and on the interstate and have averaged 24.9 mpg since I've owned it. It doesn't handle well in rain - tires spin. The trunk always seems to bonk me on the head when I'm putting stuff in the trunk. Both side mirrors have had the trim fall off - once by closing the door and once in a car wash! I had a big piece of trim fly off the underside of the car too. Every time I pull into a parking spot with a curb, the underside is so low it scrapes. The brakes have whistled since shortly after purchase and I had the "dust" removed once at the dealership for $300 (not covered by warranty!) and within a month it was happening again - doesn't seem to affect performance.
Shifter is cool (even though it is an automatic), looks cool, accelerates well, comfortable back seat ride and good leg room.
Different brakes so they don't whistle, better attached trim, better lift on the trunk lid so it doesn't sink and hit you on the head. Spinning front tires in rain is a problem.
