My name is Nick. I currently own a 02 Buick Century. I love Buick in general. But anyways, I might be trading my Century for a 07 Corolla CE. So I'm just trying to get some knowledge about gas mileage and how reliable the motor is. My Century only has 102K on it where the Corolla has 147K on it. Blue Book values the Corolla about $1200 more than my car, so i would be paying a little on top of it, but I'm really looking for something with good gas mileage.
