I have some water vehicles showing up on the map (I just finished Level 7 story mode), but when I got there by Superman they're not there for me to buy.
Is it a must for me to use a water vehicle, drive to those points so that the vechicles can be spawned?
BTW thanks for the detailed list.
All my played games are exactly 1000G! I'm a 1000G completionist.
I hate DLC achievements, since they always ruin my 100% 1000G record.
