Mission 80 – Destroy Boosted Car Shipment
Head north to find a smallish operation filled with cars that need to be blown to bits.
You can either sneak-kill the guards and then detonate at leisure, or combine the two by freely tossing around some explosives (there are many free-standing gas canisters, and a fine selection of replacement molotovs close at hand).
Don't forget to grab the cash before moving onto the next mission.
