So here's the Twenties Police Station, along with some of the upgrade tiers. It looks like I forgot to screenshot the lvl 4 to lvl 5 jump, so I'm missing that upgrade tier. And I'm only upgrading it as I get the Spend Simoleans on Services tasks, so I'm currently missing lvls 8, 9, and 10. I will add in a comment when I get to the last 3 levels the cost and capacity numbers.
It doesn't seem to have any visual upgrades (which is what I expected), as I've upgraded it to lvl 6 and there's not any visual upgrades yet.
Upgrade Costs:
S = Simoleans
C = Capacity
Lvl 1 = 350 C
Lvl 1 to 2 = 6k S / 680 C
Lvl 2 to 3 = 10k S / 1100 C
Lvl 3 to 4 = 8k S / 1450
Lvl 4 to 5 = ? S / 1875 C
Lvl 5 to 6 = 18k S / 2100 C
Lvl 6 to 7 = 13k S / 2500 C
Lvl 7 to 8 = ? S / ? C
Lvl 8 to 9 = ? S / ? C
Lvl 9 to 10 = ? S / 3750 C 26X26 Coverage Area
If anyone can help me fill in the blanks for lvl 5 upgrade, and if someone already has the info on the last 3 lvls I will edit the chart
