A discreet location

[katsuragi]

In story mode I'm doing the first real heist with all 3 of our heroes. I had to grab a Tow truck, a garbage truck, 3 boiler suits, and 3 masks. Now I need to hide a 4 passenger car in a "discreet" location. Problem is.... where? Where is the heist taking place? ummm... the airport I think? I'm supposed to call Micheal to give him the getaway car location but no matter where I go the only option is "Hang Out"

Where am I supposed to put this car?

"This vehicle can be used as a getaway vehicle. Hide it in a discreet location. Select the "Mark Getaway Location" option when phoning Micheal."

That's it. No clues as to where on the entire map I should go. Again I think MAYBE this is going to be at the airport but that's just a guess. What I do know is that "Mark Getaway Location" is NOT an option when phoning Micheal.

if you are familiar with gta online theres an import export garage in murrietta heights where you can park it

You can drive to places you would take a hooker. You will get a prompt that says this is a good place to stash the car and you can then call it in. I've done it a few times using different locations every time.
