Do people who buy these usually resell them after building or do you just end up with R7000 worth of plastic blocks on your shelf?
So it depends. Some people choose it as a hobby. A project of this size can take about 30 working hours to build.
Some people will then break down and rebuild their sets continuously. Others build once and keep them as models.
Some people may resell, others hold onto it for some time hoping it will appreciate in value as collectors items.
For me personally, it's a reward. A huge achievement deserves a set. So when I look at the sets I have on display, it's a reminder of what I have achieved.
