i haven't i was close to finishing the green car quest but when i got to the fireworks part i decided to wait until i finished eating to do that i come back and do a players quest and when i decided to do the quest i opened the explore map and got the message about the car quests being changed so yeah...
Well, i have them all except the green car. Cant get that fireworks score. Then i started thinking. Whats the big deal? I mean there is no advantage i see to having the green car. I mean its not like the space pin, which you need to get into certain rooms. its just another color of car. So what? So, i stopped stressing and i will use one of my other 3 cars when i want to drive lol.
