Biggest thing I notice are no more LED tailights (lol) but, SE and SELs get standard remote start, push button start, and smart key access now. SE's get sync 3 standard now too. Titanium get standard 19" wheels now.
Most annoying thing is the vista roof is not a stand alone option now (On the SEL its only packaged with the old Titanium wheel).
But, then again this gen is on its way out anyways.
