Notes from the workshop floor

Motarchive is written and edited by S. E. Parker — A strong interest in cars, pre-war to modern led to the creation of Motarchive. Having been exposed to cars as a young child, a fondness grew for anything 4-wheeled particularly the beauty in the function.

The journal began as a notebook: somewhere to document my own thoughts on select cars with a fresh insight on to the more technical side. Many blogs show cars as just objects of beauty, with this project I continue to show the beauty behind the body and the history of how they came to be.

When not writing, Parker is either looking for the next project, working on a current one, or photographing cars, nature or just something that catches the eye.
