Basically I had a Car Meetup with someone of the forums here and they had this car in their garage:
The only way to get it is to START A NEW CHARACTER ONLINE AND PICK IT IN THE TUTORIAL RACE WITH LAMAR.
Then you would have to take it with you all the way to the point where you have to pick your own car, add a Tracker to it and insure it.
Afterwards someone would need to do this glitch:
INVITE ME TO YOUR PRIVATE GTA ONLINE SESSION OVER XBOX LIVE THEN.
I will store $50,000 in my wallet, you kill me over and over again to pick up the money and I also transfer some of my money (idk what the max is, probably around $9k?) to you.
I don't know when I will be available today to pull this off with you, but if you have stored this car in your garage and would be willing to do the glitch in a Invite Only GTA Online Session with me then hit me up.
