I've been restoring my old daily driver, a 1985 Mercedes 300TD (the model has appeared in over 1000 films) for the past year. It's a funny questions to ask what is fully restored, is it all original, or OEM. One day I'm flexible about a piece of plate steel used for the fuel pedal mounting bracket and then the next day I'm feeling like a fraud for replacing the floor mats with after market. Either way, it's a rewarding process to bring anything back to a useful state. My Fixit shelf in the basement is a huge draw for my free time.
