recently boughy a chevy optra 2003 1.8l looking for a good mechanic shop that can get parts at a good price and also does good work. need a place where they can speak english and not try to rip me off. i just recently had oil change, oil filter/air filter, spark plugs etc also told i need drive shaft, absorbers and i think a new coolant cap since mine is leaking when engine off. Im in bukit jalil so if any near here or sri petaling be nice or near kepong.
