Points taken. But I compared the above B class hauler to trade for a C class hauler that landed in the space station where I am docked. It did not have as good bonus for the shields and manoeuvrability BUT I would have needed to put 13M to trade to it.
I have spent around 30 minutes or so buying from ships that land and the space station and done a lot of repairs and many of the slots and yet only spent around 1.8 million.
Unless I'm getting this wrong I am getting a better deal, and enjoying the fun of doing the repairs, by not trading with what I have.
I did note that the damages slots are not factored when trading, hence why I only bothered to get the engines going needed to get me to the space station.
