Model car most frequently refers to scale miniatures of real production vehicles, designed as kits for the enthusiast to construct. They can be created in plastic, die-cast metal, resin, even wood. The best kits have incredible levels of detail, even in parts unseen when the finished model is on display. Major manufacturers are AMT, Revell, Monogram, and Tamiya but many smaller companies abound.
The model car "kit" hobby began in the post World War II era with Ace and Berkeley wooden model cars. Revell pioneered the plastic model car with their famous Maxwell kit derived from a toy. Derk Brand, from England, pioneered the first real plastic kit, a 1932 Ford Roadster for Revell. He was also famous for developing a line of 1/32 scale model car kits in England for the Gowland brothers. These kits were later introduced by Revell in the U.S.
Today, many of the classic models from the golden age of modeling have been reissued. Not only does this allow modelers to build the cars they always wanted (but couldn't obtain or afford), but it tends to lower the prices of the originals. In some cases, the classic models have been issued with all-new tooling, which allows for even more detailing that comes with modern manufacturing/design methods. These include AMT's 1966 Fairlane and 1967 Impala SS, and Monogram's 1967 Chevelle and 1965 Impala Super Sport.
Today, these companies are still in business, fueled by a renewed interest in model car building and collecting. ERTL took over AMT and MPC which are now both under the Round 2 LLC name. Revell and Monogram have merged. Modelers today can take advantage of modern technology, which includes photo-etched details, adhesive chrome foil for chrome trim, wiring for engines, and billet-aluminum parts. Many builders today can take a basic kit and detail it so it resembles a real car, in miniature.
