Well they just flat out turned jazz into mirage except they changed the color to silver instead of white and left of the #4 off but thats what jazz looked like down to the paint theme and thats about how jazz acted i know they did away with jazz in the 1st but they intentionally do that to get on peoples nerves.. because mirage was a Indi car or formula 1.. but here is tidbit whenever he tells dude after they get done with the mission that he could sell him and the 1st car he turns into is what wheeljack is supposed to look like and the second car he turns into is a race car is what mirage really looks like.
He sure looks an awful lot like left the #4 off it even the personality was that of jazz but as usual thty intentionally do stuff like that to make people mad why else would they do it.. because mirage was a formula 1 race car or a indi car .. they basically just switched jazz and mirage.. bec thats exactly how jazz looks and acted
