No, it becomes the base ship that was the original. All CCUs are removed and cannot be rebought. Which is why you have to be careful to not melt a CCUed ship unless you really want it gone.
You can actually melt the Connie as soon as 24 hour period is over and immediately buy the Blade. Buyback is not dependant on being for sale. Which is why I'll be buying/melting a TON of Prospectors once those are available. I even have a few Blades.
Don't ask me why he'd want a Blade though...
True. There are ways to get a CCU, but even those are above what should be cost. Not $100 more, but we're not 100% sure it's going up in price and therefore a gamble. (Even though we know it's 95% guaranteed to go up.)
I'm late to the party. I actually found those original videos on YouTube as well and have meant to start learning.
At the moment I have:
Crashed a Hornet without leaving the landing pad.
Become best friends with asteroids.
And never able to kill anything without weapons overheating first.
