Hey there folks

I just started the game and I enjoy a lot of things about it. But there is one thing that concerns me, that is the C-Store. Now I checked it yesterday and I saw this huge ship which cost 2000 C-points. Now here is my question:

Can you get the best ships in the game by simply purchasing the ships for real money, or can you actually earn such ships in-game without paying hundreds of dollars on the huge ship. I know you need a rank to get it, but still, if its the best ship in the game?

Anyone can tell me how the C-store ships works compared to the ships in-game?
