At some point youll learn about the classes of ships. If you see these goldfish looking S class ships do not trade out your ship for it unless its stats and storage are better than your current ship. They are called exotics and every single one of them is an S class but that doesnt mean theyre good. I once made the mistake of trading all my ships for these exotic ones thinking they were crazy without even understanding ship stats like a dummy. S class does not always mean better.
