I have had my Sentra for a little over 2 years now. At first, I thought it was a great car. It seems a little wimpy as I have had other 4cyl cars with more guts. The factory tires wore out after 15,000 miles and it seems like there isn't a shop that can do a proper alignment on it. It tracks to the left and when braking at highway speeds, the steering wheel shakes bad. The interior looks cool, but isn't built with the highest quality. I would not recommend this car to anyone. The only good thing about it is the gas mileage. I get 31.5 mpg on average.
Exterior design. Gas mileage. 6 speed manual (the only fun part!).
