 I love this car. Mine has the 2.0 with a 6 speed.  I THINK that it shifts really smooth.  handles well.  I have smoked the newer hondas with this.  in the civic it comes standard with a 1.8 and the si has a 2.0.  well with a sentra you get a 2.0 stock.  so i think it has the best standard horses. the interior is quite comfy. i drove it from ohio to texas and was really comfy.  the base stereo has really good sound for a semi- base model. this car has a really big trunk.  i can easily fit 4 12 inch subwoofers in the back!
