Finally figured out how to get the Vapid Dominator!
It took a while but it was totally worth it.
IF you have completed the story and want some unlimited mustangs what ya gotta do is within these steps
Take your character to a spot where cars are spawning and driving by constantly.
Quick save your game from the cellphone.
Go to the pause menu and go to "GAME" and click where it says 'Replay Mission' and search for the mission "The Wrap Up"
Finish the mission, right before the end, there will be a parking lot where MerryWeather has set up shop trying to kill you and dave. You gotta clear them out and make sure all choppers and MerryWeather troops are gone.
(5). DO NOT steal any of the MerryWeather cars, You want to run to the end of that lot and you see a parked Vapid Dominator (Will be in various colors) next to a wall. Get in the car and outrun the chopper chasing you.
(6). Proceed to complete the mission and once its done after you talked to trevor the screen will go black therefor teleporting you back to the spot where I told you to go in Step 1.
(7). Look around for a Vapid Dominator because they will be spawning around the city (it will take some time to find it but i swear there will be some around. I've tested this NUMEROUS times to be certain and it works EVERY time.)
(8). Once you find your Vapid Dominator, you want to bring it to your garage, (NOT your home garage.) The garage you pay for unless you got it with a special edition or collectors edition pack. Just be sure you dont bring it to your actual garage at home because IT WILL disappear and then you have to do it all over again.
(9). Leave your garage, Save your game, Walk back into your garage, and there ya go.
(10). Once this is done Vapid Dominators will be spawning everywhere around the city, grab some, customize some, have a blast. Hope you guys have fun and I hope it works for you like it did for me.
