The errors in name spelling on these models are quite simple to understand: these toy cars are now designed, engineered and produced in China. The various companies marketing these toys or models now rely entirely on Chinese companies to produce and deliver finished goods, with no other intervention from them than producing a purchase order and a leter of credit.
So, as for Tamiya and many other Japanese companies in the 1960's, joyously mispelling so many English words and names, it is now the turn of the Chinese to do so.
Some here will remember the famous Tamiya "Lora T70" slot car kit...
And yes, they DO care, but they often rely on hard-to-decipher available documents for their research, and while they would be well advised to check the Nostalgia forum time to time, there is no Chinese version... :\
Think of the reverse situation and you would have pretty much the same problem!
