In his post, goofyone described these as "alpha production builds, beta production builds, and finally production builds". I suspect these, alpha and beta, are the ones produced during the first 90 days, and the final production builds is what happens after 90 days when they are running full speed. I believe these, alpha and beta, will be the ones we, the reservationist, will receive. This is probably good. These vehicles will receive more hand care, attention, and numerous inspections than those produced after 90 days.Wonder what happens to the alpha and beta vehicles. Maybe some lucky factory workers get to take home a door prize?
