Concours restoration is car restoration taken to its most extreme. It involves restorative efforts that can be so extensive that the car is practically rebuilt from the ground up. To the best of the restorer’s efforts, only original parts are used in this type of restoration; exact replicas created to the very same specifications of the original parts are substituted only if and when no original parts can be found or sourced. The restorative work itself is done with the utmost care to keep the finished product as close to the original specifications and condition as possible. No detail is considered too minor in the restoration; neither is any expense spared.
Restorers typically start out with a comprehensive evaluation of both the unit being restored and its make and model. Service documentation and history are a must at this stage. Then, based on the findings, the car is gently taken apart and stripped to its frame, which is then cleaned and repaired if need be. Every single piece of the car is scrutinized very closely and then worked on, including the engine, clutch and transmission. The alignment of various parts, from panels to seals, is checked to see that they not only look good but also function properly. Rust is removed and each part is treated to ensure water resistance and durability. The interiors, including the seats, carpets, panels, and dashboard, are also restored.
After everything is worked on separately, the next step in Concours restoration is the reassembly of the vehicle, which is also performed to the same strict standards. Complete checks are performed to ensure that the car is in perfect working order. Finally, the car is examined minutely one final time to ensure that it is no less than perfect.
