Getting firsthand information from an actual car owner is one sure way to get an idea of car performance once it leaves the lot. Autobytel features real consumer reviews that give the unbiased experience of a car.
Nissan Sentra lists gas mileage 27city/36 hwy. - not true in my experience, lot less esp. city. Secondly, car comes automatically with some "features" that I am not interested in & sure I'm paying for. Thirdly, some features do not work properly, i.e. phone option does not sync up with my cell phone; in "eco" mode my car revs at stops - do I don't use feature; buttons on steering wheel get in the way & accidentally get pressed; I don't need USB port.
