The difference isn't really that bad.
The pricing/options config is strange.
A 2013 28i with the following options:
- Premium Package
- Xline
- Lights Package
- Power Seats
- Parking control
works out to about $44,395
A 2012 with the following options:
- Premium Package <--includes Xline
- Lights Package
- Park Control
- Power seats
works out to $44,485
