True, like there examples:-
Hound and Swindle Jeep mould differences:- tyres (smaller tires, large offroad tires), paint work (Hound green, Swindle yellow), head, number plate
Mirage & Hot rodimus: number plate ("Mirage" and "too hot"), paintwork (blue with racing stripes, red with flames), head
Shockwave and Jazz: Number plate, Shockwave left arm has a blaster, head, color, different bodykit (shockwave has mazdaspeed bodykit, jazz stock car i think)
Grimlock and Wheeljack: number plate, head, paintjob( silver vs white with blue racing stripes)
repaint means they use the same old mould and just change the color. BB08 and cliffjumper is a very good example. Recon barricade and police barricade, movie leader OP and NWOP are among the other examples. But Blt and Alt they change enough items to make them unique from one another.
haha...got such definitions? i will take note of this.
