High Quality Content by WIKIPEDIA articles! A model car is a miniature representation, or scale model, of an automobile or similar powered vehicle, reproducing the proportion, shape, and details of actual production vehicles. Other miniature ground- running vehicles, such as trucks, buses, etc. (but not railroad trains or tracked military vehicles) are usually included in the general category of model cars. The line between model and toy cars is not well-defined; some toys can be scaled and detailed well enough to be considered models also. Miniature cars which are poorly proportioned or lack significant detail are usually considered to be pure toys rather than models.
