Noob is a Factory (I use the term factory loosely as all parts are assembled in different places then basically brought together.)
But Noob is the "product/making house" if that makes sense?!

Other well known factories are JF (aka J12) and also V6 Factory as well as BP Factory. I think those are the main ones!?

I personally like InTime (Ryan) - GREAT communication and super fast shipping. ToroBravos is also good, as is Sead/SuperMirrors. PureTime is the oldest in the game, but also the busiest, and generally the highest prices.
