if you say just first 1000km service i think other nearby your area should be able to perform that...if not mistaken setapak got 3S center for proton..can go there for the 1000km service.. but if you got other complain or others things that you need to change. can go COSE. but make sure you took half day...or one full day...make sure you call cose make appointment on early 8am. reach there 7.30am give to reception register early. then most likely if  one service 1 hours ++ will be able to make it...if got problem complain...take longer time. try to make your appointment not on the friday...cause friday got prayer...you will lose 2 and half hours there waiting... 12 ~ 2.30 or 2.45 they resume operation.

So far, these are the mods I have done.
