I'll likely go with Billet for a HA. I agree the Granite is "richer" looking. But I still choose billet for several factors:
1 - I'm surprised no other Altitude or HA owners have mentioned it... the DAMN chrome around the windows doesn't show hardly at all on this color. Sticks out like a very sore thumb on any other color besides white.
2- Much easier to keep looking clean. The Granite looks great clean. So does my True Blue. But just 1 or 2 nights of dew and dust and it looks fugly. I really like dark colors, but in the long run the billet will look much better. Had a dark green and then a silver Ram truck. Can't tell you how many times I had to buff that dark green. The hell with that, I'm too old.
3 - I've always liked the contrast with the black and especially the black chrome. Those black badges would be removed as soon as I got it home so they don't even matter.
I wish Jeep would get their act together and lose ALL the chrome including inside. Black chrome in just a few areas on the exterior. And could someone give them the part number for black chrome lugnuts? pretty sure gorilla has them available.
