To start, the first post here is talking about the middle row...and then posts after seem to think it's the third row.
The third row 2-passenger (which some think of as buckets) is completely interchangeable with the 3-passenger third row. In the middle, the buckets and bench can be interchanged, but it's a much more in depth take-out and re-installation--which is why dealers don't want to do that (in addition to then having another vehicle that then is missing a feature on it's sticker, etc.).
So swaps can be done of both rows, but you have to have either a very willing dealer who has a matching model with the right seats on their lot or simply do a swap on your own with someone else.
I really want bench seat, but I don't even think LTZ's have the option for bench seat....anyone??
YES. Middle row buckets are standard with the LTZ, but the center bench is then available as a no-cost option (while standard, in the opposite way, on all other trims).
