official sc... sure kene scalplah..... i mean, isnt everything expensive there?? added on stuff like body kit can go up to 10k.... then they can advertise, "pomo 15k discount" (discount as in free bodykit, rims and maybe one or 2 other minor differences)
u can find nice ones punya.... otherwise just get a set of taiwan rimslah... long as within spec, no real downside (not like its so fragile that a minor bump cracks it, you are not thinking of super low profiles anyway)
1)prices are around that figure... maybe abit cheaper.....
2) google is there... you can calculate how much the insurance and roadtax will cost u....
there was a quote by someone here.... cant remember who, it goes: "if you have to ask, you cannot afford it"
