MOC simply stands for "My Own Creation" and is a term used to cover all the fan-based LEGO creations other than the officially released sets. Rebrickable stores thousands of user-submitted MOCs all with building instructions.
So, one question. Every time I'm looking at the parts list for a MOC, the price is even higher than Lego. I just looked at a F1 Ferrari mic with roughly 3000 parts and the price was an estimated 930 bucks.
Any best practices or advice?
Oftentimes, just a couple of pieces are responsible for the high price, because they're rare in the specific color being used in the MOC. Sort the part list by price, and you'll quickly be able to identify what the problem is, and see if you have similar pieces already that'll do the job, or if you can just substitute a different color that's cheaper to get, for example. It also helps to have your own collection logged on rebrickable, as it'll show you how many of the required pieces you already own!
