Sorry Bro you will need to search for the things you want in 0.3x.I don't think you will get the permission.
yes sure you will not get
because you are boght vehs in 3e
you cant buy vehs and buyable things in 3x
you should pm any beta tester and magement to give permission
i think it is not allowed but i have idea if you not like 3e you can move to 3x you score and mq/cooki,played time will be there
dont worry
