Yeah she was raving about that initially. She was telling my wife: "They use autocad, and can do anything you want" as if no one in the world had thought of that before 
My wife bit her tongue as to not inadvertently "offer up services"
From what I gathered, they had "designers" and "interior designers" to help you pick your selections.
The way I figure it, they have several seats of AutoCad, several drawing monkeys, and a lead monkey somewhere. Likely a single location. So you've got licences and payroll there, then each "design center" likely has some person that may have attended an interior design seminar they put on nationally. That's overhead in each sales location. Then salesmen/women (much like a car dealership) plus model homes that can't be turned into residences because they're on the side of a hiway and not in a neighborhood.
Sounds like they're offering modular home quality at ACTUAL custom built pricing
