The FBT exemption incentivises the common crop of dual cab utes. Those are Hilux, Ranger, etc.
The much larger F150 shown here can only be had by first importing from the US and then converting locally to right hand drive. The associated engineering certificates and approvals are non-trivia. By that point they’ve picked up the luxury car tax due to the costs involved. They also attract a higher registration/CTP fee due to weight and risk.
So, they’re actually heavily disincentivised by taxes and policy. That’s before you even look at the cost to comprehensively insure. Very steep due to the substantial repair costs driven by parts availability.
