They do a car in a week with four people at no cost (that I'm aware of) to the owner. They have to make decisions on time, materials, and budget in a very compressed schedule. Some of the cars don't get all the spit and polish that they need because of that. You don't see them doing a lot of body work because that is a huge time sink. In the end they get the car going safely down the road. Leaving some of the orginal parts on there is part of the game in order to get done. The bald dude that does the electrical knows his chit.
