Source note: each cell is cited individually. "Unverified" means we haven't yet found a source confirming or ruling out sales in that market. It is not a claim that the model wasn't sold there. NZ was a major used-import market for JDM Land Cruisers, but new-vehicle NZ sales are mostly unverified here. Market names and years cover new-vehicle sales by Toyota/Lexus distributors.
