I traded my full size 08 Titan 4x4 in on this car because I refused to pay $100 for a tank of gas. Very, very painful decision. But in the end, it was the right decision. I looked at all the economy cars and happily decided on the Sentra. I haven't had any problems with my Nissans. This car has nice room for its size (I'm 6-4 and 36" inseam), pretty good quality manufacture, good power, 31-33 mpg, and handling is good except I get blown around pretty good in high winds and behind semi-trucks. I got a great deal on this car.
The keyless system is cool. Can't believe I didn't have bluetooth before. I like the split trunk and fold down rear seat. All cars should have the mp3 plug-in socket. All the airbags. This car just looks good.
A little better gas mileage would be nice. Better handling in windy conditions is not too much to ask for. Maybe a longer arm rest.
