In around the same time I also built a stock 8408 from Brickshelf scans, substituting white for yellow. (Both cars share the same Brickshelf folder.)
I presented the pair on Lugnet, and it got referred to in several places in discussions about studless Technic. Just as I intended. ;->
The pair is, so far, my only MOCs that I don't have to go buy parts to complete.
