Movie Masterpiece Jazz was revealed alongside Movie Masterpiece Megatron at a Hasbro China event in January 2019. Unfortunately Jazz was only in the first live action film but this figure is the best representation of his only appearance, complete with his grizzly end.
Jazz was released in September 2019 and retailed for $89.99 which was rather expensive for its size however in my opinion Jazz is one of the best Movie Masterpiece figures so far.
Jazz's vehicle mode is a Pontiac Solstice concept car which was showcased in 2005 at the SEMA (Speciality Equipment Market Association) show. The original was painted a gold colour but for the 2007 live action movie this would be replaced with a metallic grey colour.

Unfortunately Jazz was not able to have his original Porsche alternate mode but there was a nod to this in the live action film in a scene where Sam and his father were looking to buy a car and drove past a Porsche garage. Despite not being a Porsche however, the Pontiac Solstice is a reasonable substitute.
