I have a new 2015 RX 450h Base (Comfort and Premium Packages) and was looking to convert my existing front-end bumper to the 2015 F Sport bumper (had no idea this was an option or I would've gotten it). Does anyone know what's required to do this? Parts list? Cost? I will definitely need to have a body shop do this for me as I'm not automobile-savvy.

I've seen other threads where 2010 RXs have been converted to 2013 F Sport front-end. I'm hoping this is easy, but I have no clue what it takes or costs. Anyone out there know who can help?
