So is it that the 2wd xe are I-4s while the 2wd se is a V-6?

Are there certain features only availiable on the se and not the xe?

Well this one is silver, has I think all the options( running boards, stereo ... ) Exterior wise it is in perfect shape, I haven't found a mark on it yet, the interior is almost perfect except for a mark on the steering wheel. I have the dealership talked down to 12,900 out the door with a 4 year extended warrenty bumper to bumper warranty. I have not run a carfax on it yet. Also how do I tell if it was heavily offroaded?
