There are ships you buy for a specific purpose, ships you buy because well, shiny! There are ships you buy because you simply want to try them out and see what they are like to mess about in. You'll refit most of them several times and entropy dictates that on at least some of them you'll end up with the most insanely goofy and impractical loadouts for a while.
Along the way you'll get to really like some of them and their particular configurations. To the point where even though fitting a different module is the right thing to do for WHAT you want to do, it still feels like the ship "isn't as good" like that. This would be the point at which you've discovered a new member of your "permanent fleet" and rather than mess with that one you go buy another.
You can do this by periodically grinding credits as you need them, by taking a relaxed playstyle and just letting the credits accumulate on their own, by looking at your ship list from time to time and ruthlessly flogging the ones that aren't on your ever-growing "favorites list" or any other way you like. Just, once a ship has made it onto that "permanent list", dont ever be tempted to sell it "because I can always buy it back later" for the latest shiny and always keep an insurance cushion not just for the ship you're flying but for the most expensive one you have in the hangar. This isn't vanity, it's ensuring that when some aspect of the game torques you off - and sooner or later some aspect of it WILL, even if you've seen it all before - you never find yourself "having to keep doing it". There will never be anything to stop you hopping into any of your other ships and doing something else.
