I get that LandCruiser series can be confusing. You need to understand there are the "Luxury" Wagons which include the 100, 200 and now 300series.
Then there are the utility workhorses which are basically the 70 series which is very basic and did not have airbags in Australia until about 2010. Any vehicle in Australia of 2000 vintage would have a 4.2L straight 6 single turbo diesel, many believe (myself included) that it was the best engine ever in the Landcruiser 70 series.
The 4.5L V8 single turbo diesel engine was introduced in 2007, it just does not have the punch of the previous straight 6.
In 2024 Toyota introduced the 2.8L 4 cylinder diesel with an auto transmision (prior to this they all had 5 speed manual) , due to immissions issues with the V8.
Currnetly running a 2008 4.5L V8 single cab with tipping tray.
