maybe the right brain/ left brain thing comes into play. i know some real cars (and the artists who creat them) may have a great deal of imagineering built into certain components, but if it's going to track straight or not succumb to mechanical vibration or excess wear, there has to be a substantial degree of acuracy in certain places.
but my initial comments were mostly directed at wordsmithing which, although i didn't consciously make the connection, would help the story flow. if i am reading, evidently i am reading in scale, and when i hit a dimension that may not have scale relevence, i have to stop and see where it fits into context which interupts my train of thought.
buider: i just chopped my deuce 1/4"
reader: 1/4" in 1/25 scale is about . . . . . gee, my exacto blade is thinker than that, he must have used a laser..... oh! he means almost 6 scale inches. bitchen ride, dudette!!
