 I am a new owner and very pleased with first month of driving.  I am 6'5" an 275#  - too big for most cars and so have been driving vans/pickups - but I tried an Altima at an autoshow and found I fit great in this car.  I have only owned for a short time but so far the Altima Hybrid performs well, has a quiet comfortable ride, gets good mileage (now averaging 31+mpg driving aggressive) , it seems to have good build quality/materials - I got convenience package only.   I also think it is remarkably fun to drive  - far more sporty  and quick than my wife's non-hybrid 4-cyl Accord.  Also runs in whisper quiet EV mode up to around 25-30mph - which is lots of fun on twisty rural backroads.
