Low precision, average quality, soft and cheap brand. A good car model is first made by a professional model manufacturer authorized by the owner of the imitation car brand to obtain very detailed real car data. After careful research and development, some advanced car models even use the same paint as the real car, which will produce a fine collection. Some limited editions also have extremely exquisite packaging and collection certificates, and some models of F 1 have drivers' autographs, so the prices vary greatly.
