being now 21 and growing up there i think i can comment.
helz - bad post about s.a. not being rich, its pritty much is and most people can live fairly well, i lived better there than i do now. Dont get me wrong i am british born and bred, just parents moved out there but now im back. There is still racism, but to the point you dont notice it, you can say the same about living in the uk.
popular cars there are the golfs, people love them there, especially the gtis and the much larger ones inc v6 etc but nothing like i seen here (been back for 7 yrs)scoobys, evos, coup's etc
