yeah looked at a gov car website and they seem to sit at about the 18-20 mark too. I dont think its too crazy

I just found the car advertised on carsales

carsales car

They also offered for another $2000 they would include tinting, cargo barrier, stamp duty and their own "after sales" extended warrenty.

Considering tinti is about $300, the cargo barrier is about $300 and stamp duty is $577.00, that means their dodgy warrenty is about $800 dollars.
whih is not bad really
