This year Lexus introduced the RX-L which has a 3rd row seat. So, you might consider that for your list of luxury 3rd row SUVs. One of the two cars we recently leased was the 2018 Lexus RX-L. We paid $509/mo plus tax ($542 incl tax) and zero costs due at signing except the first month’s payment. Details here: 2018 Lexus RX 350 and a 2018 Lexus RX-L
