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!
6 speed :)
for those who have a little money to invest. i would recommend installing some coil overs as well as a front and rear sway bar to improve handling. i would also add a cat back exhaust, a cold air intake and chip the computer. this would give the sedan alot more bite!
