I know how to get Wang Cars, e.g Cesar's Missions.
I've completed all story missions and are up to the next mission after beat up B-dup (CJ & Sweet). I tried various times to get Wang Cars buy still said I can not buy this yet. Does it have anything to do with Cesar calling you to take care of the cross country courier in his cellphone call? i did a couple of them.
I completed Zero's mission and have RC shop as Asset (airfield too) but i can still go inside RC shop to play around with the RC red baron plane.
Anyone with some help on this would be great.
oh yeah
GTA-San Andreas Site didnt tell in full detail how to do it, it just said it should unlock after completing certain mission.
