In each city, find a parking lot that can be secured with a gate, which can then either be hacked like the bank vault, or blown up with satchel charges. Inside this gate there would be multiple high end vehicles, which need to be stolen and delivered to the docks in each city.
Payout for each vehicle delivered would be 15-20k. There could be at least 4-5 cars per parking lot.
Maybe one vehicle out of the 4-5 would randomly contain an additional valuable package that would need to be delivered to a mid way drop off that would award an additional 5-10k.
Would give crims something interesting to do aside from rob the bank.
