Depends. If it looks really similar but isn't actually based on an existing car, then they don't have to pay licensing. For example, Universe/Henkei Sideswipe, Sunstreaker and Red Alert transform into cars that bear a strong resemblance to the Lamborghini Gallardo, but they're not actually entirely accurate, so it wouldn't have bore any licensing costs. Alternators/Binaltech, Alternity etc. on the other hand are all based on licensed vehicles and thus HasTak would have had to pay for them.
