i just unloaded at it with the MP7 and it span out of control and crashed. make sure you run to the lower building directly looking along the street. you wont be able to stop him if you stay at the sniper nest.
you should get get a waypoint after the van leaves the garage and your buddy should start running to intercept the van.
just empty a mag into it from the roof beside the street and it should crash. if he escapes just try again, its easy to repeat due to how close the van is to the sniper nest :) --- WHAT HAVE YOU DONE TO MY TOPIC???__carwreck__ [REPAIR 85] Helios one cab give peer too if fixed.
