When restoring a classic car, a major part is the engine. The engine is the heart of the car so it’s advisable that a certified mechanic is given the responsibility of repairing it. Once the engine starts smoothly, you can steam wash the compartment of the engine and also repaint it. The gearbox and the transmission is the second part which needs to be checked. Changing the oil in the transmission and gearbox is suggested. Next in line are the body panels. Rusty or damaged body panels should be replaced.
