Finally have my '15 Limited looking like I want, after a year. It took a while because my buddy painted the pieces for me and he is busy.
I could've, and maybe should've bought an Overland, but I didn't. I really enjoyed the process of modding my Limited, and would've found things to change on an Overland. But I will probably buy an Overland when I replace my current GC.
My first mod was tinting the front windows, then replacing the vertical grill inserts that come on the Limited with the black mesh inserts. I then added the chrome tow hooks. Later I replaced the black antenna with the white one. Next I replaced the chrome door handles with white ones. Then finally, I replaced the front and rear lower fascias, fender well trim, rocker panels, mirror covers, and roof rails.
Here are some not so great pics, but you get the idea nonetheless.
