Find an engineer, recreate a spy, and then find an American soldier. Then let American soldiers take a taxi (press ctrl), and the parking lot will cost a lot of money. Don't fix it yet. Put the engineers next to the garage (don't go in), put the spies away, and then select all these guys. Press the Z key (route point) to select a place next to it, and then click the injured parking lot. Then the car was upgraded. With this skill, you can steal parking lots, barracks, battle laboratories, power plants ... not in Yuri's revenge.
