About the ship purchase, befoure buy ask around or in Discord, in TEST we defenetly have more ship them member, so there sure be someone that can lend you the ship you are looking for to try it out.
Also you can rent ships in game, pricy, but can be wort if you won't to start grinding money with them, and soon [tm) there will be the first implementation of persistance in game, so your money and purchase will stay there... and this mean you can actually grind money and purchase ship in-game.
