I have pretty much a basic SE. I went from a loaded Suburban to this...........I had everything on it. that being said, I don't really miss the moon roof I had.......I live in the country, so I didn't have the opportunity to open it as much as I would if I were in town for sure.........so, I didn't get one. The only thing I added to mine was the lighting group. I would REALLY miss that if I didn't have it on a vehicle. The only thing I have found I REALLY miss from my suburban is a switch in the back end to lock/unlock all the doors with the hatch open. I do miss that. I like the push button entry system though........
After driving a Suburban for 5 years........backing up with this is a dream.........I have SO much more room to manuever! LOL...........
So, I guess, for me, it is the light group.........lol. I don't even miss my leather seats much. I do alittle........I have to be honest. I miss the wipeability of them.
I would get leather in the next one, but I already know I can add it to mine at any time for about $1300, so that may be my option. They tell me they look even better than factory seats when you have it done. I saw someone had gotten 2 tone put in on the gallery page........I think I would opt for that possibly like the new 2008 limited.
