Solid car so far. Purchased it on 12/31/11 and have put a little over 2000 miles on it. Averaging 26 mpg combined driving and a respectable 32 mpg on highway. As previous owner noted, it is simply styled on the inside (mine came without a radio) but very functional with good quality materials and comfortable seats. This is my first Altima. I'm trying it based on the super great performance and reliability of my Nissan King cab pickup (1987 model) I owned for over 10 years and 225,000 miles. We like what we have seen so far from the Altima.
Performance, Styling, Comfort, Good Mpg and future reliability ratings. We were also happy that it scored well on safety ratings.
Took a while to get used to push button starting. We now enjoy that feature. No real problem areas noted at this point. I will post more later.
