We bought our Sentra straight off the truck at the Nissan dealership and have just fell in love with it. It's the perfect car on gas milage and really fun to drive! The only drawback was some vibrating sound in the dash at only 11k miles. Have since traded for a larger Altima. Overall, I've owned 4 Nissans and have had nothing but great service.
Sporty design, lots of stoage pockets inside, fun to drive!
