I also wonder if the more toy accurate look is not just because of his lack of show presence, but also to bring down the cost of the toy, being a lesser known character. It's been confirmed by Takara that the more show accurate Masterpieces have higher parts counts, thus cost more. Might make it an easier sell to collectors since he's not as well known as the other 1984/1985 cars. Potentially could also be a market test to see if people are over cartoon accuracy.
