Way to unlock: You need to complete Main mission 35 (Blitz Play). There is no marker for this mission and you can start it at any location..
Playable characters: Trevor
Additional information: All of the missions connected with a new heist are very short. This one is about stealing any car and leaving it in a spot where it will pass unnoticed.
Which vehicle you choose to get away has no significance. You should pay a bit more attention to the selection of the spot where to hide the stolen car. The heist itself is going to take place in Cypress Flats (the Southern part of Los Santos, to the West of El Burro Heights). Therefore, it would be a good idea to hide the vehicle somewhere nearby. Choose some side alley, discernibly distanced from a main road (if it is a poor location, you will get informed about that). Turn on the phone, find Michael in the contacts list and select the first item on the list (Mark Getaway Location). You can now walk away from the car.
Rewards for the completion of the mission: none
Requirements for the completion of the mission in 100%: There are no additional requirements for this mission so, it is completed in 100% automatically.
