so i work at a nissan dealer and this is definitely a welcome improvement over the outgoing sentra. the outgoing model is the definition of a disconnected and boring drive. the styling only appeals to 16 year old females and the interior feels like 1990's hyundai accent. the new model at least (for now) seems like a much more modern design with a much nicer interior that only gets better with trim levels.
its not going to be anything fun to drive, but for the price and features end of it - i think it will be hard to beat.
