Interested to hear of its transition from four to two seats
I think you are getting confused with another Plus Four that is now a regular competitor, but was converted to a 'TOK' lookalike from a rather sad four-seat Plus Four..
And I am a bit puzzled by the video commentary "there is another exhaust pipe on the other side". I have never come across a Plus Four with twin exhausts - and a quick look at the pictures from the 2018 Classic only shows one pipe. But journalists rarely let the truth get in the way of a good story!
