 I absolutely love my '07 Nissan Sentra!! Lately, I have been having nonstop battery problems. In the past 2 weeks the battery has been jumped off a total of 6 times! That just did not seem like it should be happening to a car that is a little more than 3 years old. Apart from the less than impressive battery, my car hasn't given me many troubles. I've had a few variations in my MPG. Sometimes I would get around 30 MPG. Then other times I would ONLY get about 12 MPG!  Certain parts were tweaked and cleaned, and now the gas mileage is relatively normal. The car is cute and suits me (a college student)! It is also very spacious (very convenient for moving in and out of the dorms)!
