Did I hear him say it takes them about a week's time to put a TF car together? Helps, of course, if you have the skill, the parts and years of experience but I find that fact absolutely amazing. Even more amazing is watching a team take a spare rolling chassis out of their trailer, swap all the usable parts from their car that was just destroyed along with parts in the trailer, and have it ready to race the next day. These are talented people on an almost unheard-of scale.
