Good business strategy, not milking the molds. Not everyone wants the same tractor kit (they have different features). Why not offer different versions and options for different builders. I’m sure they are selling well.
They are doing the same with their G506 trucks, to lots of buzz.
I will agree this is the next in a long line, but each of the models offers something different and so I am happy to see them making the most of the product moulds.
