Why don't you let 4cyl. models have the opportunity to have the panoramic sunroof? Why only the V-6 models? Also, why even bother with the V-6 when you already have the 2.0T GDI that puts out practically the same hp/tq. with much better gas mileage. My wife has the '11 Optima SX T-GDI and that engine would be perfect in the SX and EX models.
