The Galaxie LTD car trailers are easy to build and can be customized to depict anything from a race car trailer to a classic car hauler or what ever your imagination can create. The parts in these kits are molded very well and the raised rivets are very realistic. Most 1:25 / 1:24 scale Muscle cars will fit into the short 21ft version with room for accessories and easly fit the 38ft gooseneck or tag along, larger cars like 1:24 scale 1930s Packards,Cadillacs, big trucks, etc. may need the longer trailers. All of the Galaxie LTD trailers are a great value for the money, and the 3 late 1940s Chevrolet cars they produce are also excellent kits as well as the classic Long John dragster kit.
