When I was looking to purchase my 2018 a couple weeks ago (still awaiting delivery), I saw a dealership in Chicago which has a TFC on the showroom floor. The 2020 Rockets will start arriving at the end of this month / beginning of next month.
Spoke with the local dealer on the Gold coast. He reckon's early Jan, said he had a email saying Oct then one for Nov and so on.... and that is just for his demo models
