I suspect that it might be a stipulation by Lamborghini as part of their licensing agreement. I believe this is why the bonnet forms a big flap behind the lower back/buttocks as I've heard that Lamborghini didn't want the bonnet to split. I wonder if TakaraTOMY would be able to circumvent this by including chrome stickers to be applied to the spoiler (similar to how they circumvented the Red Cross trademark with their stickers for MP Ratchet).<shrugs>
