I went digging for rust and never really came back from what is the most complex lego set ever, not really ready for how difficult car restoration is.
Still piecing together the front end. The inner wheel well is a thicker gauge support that extends from the bottom of the frame to the top of the seat bench. I extended the bottom leg much more than the factory part just to help support the frame better.
I didn't narrate this video, just the satisfying somewhat jarring sounds of restoration.
