AU series ll & AU series lll

[HarryFurner]

Hello all, have a question.
I have just purchased AU series lll Marlin black ute as advertised. On picking up the ute & checking it's compliant plate, it's is a AU series ll.
I wanted the AU lll as I believe that after AU ll they introduced the Intech HP motor into the AU lll. Am I correct.
The sell said because it is in such good condition I should be content & the fact that its black makes it rare wtf.
