Cars must meet the following four conditions, or it is just a toy car:

1. Simulation of the performance of its car models must have the original models, the original model is scaled down according to certain criteria, the proportion of common and 1 1:12,1:18,1:24,1:43,1:76 : 87, etc., most of which are motorcycles 1:12, 1:18 and 1:24,1:43 mainly cars and SUVs, 1:43 there is a small passenger cars, trucks, and 90% of one seventy-six Bus, train and train 1:87 mostly in the automotive scene, and the accuracy of the original car is a measure of the proportion of manufacturing a car models one important standard. The design of toy cars vary in size, very random.

2. In order to faithfully reproduce the actual car, the model prototype of the car manufacturer will not be the slightest appearance of modification and exaggeration, but not imagined a kind of car to. Many toy cars may also be an imitation of a real car, but manufacturers tend to produce according to customer preferences and limitations of the technology changes at random, arbitrary large. Toy designers can also launch the full stretch of the imagination to reality, not the car, but the imagination of the model is "not allowed" in the. In addition to the overall appearance of car models in the details should also be a high degree of simulation, often the entire car models by the hundreds or more components with the various components are the corresponding components of the original reduced models, scale models more parts, components the more detailed points, indicating that the higher this car models of the production process. The details of the expression of the toy car to car model is far from level, many details are ignored or the same piece of material together.

3. Cars selection of high grade metal and plastic, the higher processing requirements, the requirements of painting almost to the level of real car.
