+Luigi Luigi, the T-Boss 550 might be marketed as different brands, but in the end Linhai is the manufacturer. If take a look at 1:02 you can see on the steering wheel "holder" reads Linhai. The companies have just bought the right/license to sell them as their own brands (+ This might also boost the selling due Linhai being chinese & being sold as Massimo kind of american company, makes the brand look "better").
