I just bought a 2012 GT Premium with the GT coupe accessory package 5 that has the hood scoop, decklid panel, side scoops, pedestal rear spoiler and quarter window louvers. I got it home and was just checking it all out and noticed the glass on the rear quarter windows was a little dirty from the inside looking out. When I checked it, the dirt is on the outside under the louvers. Does anyone know if those louvers just pop off for cleaning those windows, and if so, what is the proper way to do it without breaking them ? My last new mustang was an 03 Cobra (sonic blue) and it was a screamer. I have to say that this new 5.0 is a strong engine and that thing pulls just as good as my cobra did when it was stock. I can't wait to add my own mods to this one now. I will be reading the forums to see what works best on these cars. It was a toss up between this car and an 2013 GT, but with the rebates Ford is giving on the 2012's, it was a no brainer. Thanks for the help with the louver question in advance. :beer:
