I've been trying to find examples or proofs that this expression actually exists but I just can't find any. I've heard it somewhere some time ago and it stuck in my head, and now I'm worried if it's even an expression people use.
Example: "A: Woah, did you see that Lambo?? B: Yes mate, great car that is!" With the stress/emphasis on the "that".
It is of course supposed to mean "that is a great car", but the slang would be to reverse the two parts of the sentence
