Handling, reliability, and comfort.
2008 Nissan Altima 3.5 SE
Problems: the biggest issue with this vehicle is that the dash melts in the sun. It gets sticky and tacky, and over time it has basically ruined.
Performance: this car is fantastic and fun to drive. The 3.5L coupe that I have is zippy and has a lot of acceleration for an Altima. It handles very well.
Reliability: I have had no problems at all with this car being reliable. With dedicated maintenance, this car is now 11 years old and still drives great.
Comfort: front seat comfort is fantastic with plenty of legroom. Head room is fine for me (5'6'), but if you are very tall you might hit your head on the ceiling if you hit a speed bump. Back seat comfort is fine once you are in the seat, but climbing back there is difficult in the coupe.
Features: with the 3.5L SE trim, I have the sunroof, cruise control, a decent stereo, and a fair bit of power. The only thing this car is lacking is bluetooth (but it's an older car).
