While fully fabricating a car from scratch is not a practical endeavor for most enthusiasts, it is possible to build your own vehicle from kits provided by many companies. These kits often include all the structural parts of the vehicle and detailed assembly instructions, but most kits do not include an engine or tools. Building a car from a kit allows the builder to modify or tweak parts of the design to match personal specifications.
Kit cars produced by many manufacturers are intended as replicas of famous cars of past eras, such as the many replica versions available of classic Ferrari models or the Shelby AC Cobra 289 and 427 race cars. Other kit cars are original designs that are often intended to be used for high-performance driving. Examples of these types of vehicles include the Factory Five GTM and the Dubuc Tomahawk.
In addition to full kits, some manufacturers also offer the option to purchase portions of a kit car only. Buying a kit car piecemeal allows builders to save money if they already have suitable components for a particular part of the car available or plan to substitute components if they do not wish to use the parts supplied by the manufacturer of the kit.
