don't confuse options on the Build tool of the website versus actual options available when you order the vehicle.That could be right! It could also be that Overland and Summit are both "premium" models targeting different segments and in order to keep them separated they avoid the bench seat. That's my guess, still stupid either way. As for the overland... it has had the option for a two tone roof for awhile now, the 2021 had the option.
Two tone overland is not a buildable option yet. You can't order it.
Only Summit/Summit SR are shipping from the factory with two tone.
