1. It's made in Kansas City and Lake Orion in Michigan (updated)
2. 1LS & 1LT has cloth, Leather / Suede leather seats in the 2LT's, Leather in the LTZ
3. No
4. Good question, but they also removed the fender repeater lights, and moved the dome switch to the dash.
Be sure to drive the 4cyl with the 6 speed auto, that gets you 33 MPG on the HWY. It's not a 6cyl, but it feels closer to it.
