The Dino body shells shown in the youtube video are made by CASCU in the UK or France. They are moulded from a genuine 246 rather than the other kits which all originate from the same 206. He does not sell kits and does not make them for MR2 Toyotas (see JH Classics for that). He also makes exact replica tubular chassis for them so you can part out your 308 or Mondial as the basis of a Dino replica.
This and other aspects of the video don't fill me with any confidence whatsoever - it is just a compilation of photos from the web, not any indication that the poster sells, makes or is an agent for any kits.
