based on my experience, if ur car going for repair jobs that need the warranty, then please by all means go back to proton. if u need to do normal service like changing lubricant, please, any workshops will do as long as they don't mess up with ur car that can void the warranty. why i said so? personally, i'll rather pay rm15 workmanship than wasting my time waiting at least 3 hours juz for them to do the normal servicing. past experience, not once but 3 times, i sent my brother's and sister's car to the SC center, each time i need to wait from 8 sumthing in the morning and about noon only i get the car.

like i mentioned, for normal car servicing, u can go to any workshops. u go there, if they find any problem they would tell u what it is. but then, if ur car still under warranty, u can always choose not to repair the problem at the workshop. go back to the pesc and fix it. my sis car air con kong few times 2 months after getting it. it was the fuse problem oni, the mech told me if the car still under warranty, they refuse to fix it coz scared later i come back hoot them. seriously, for normal servicing, it is really not worth the time spent at the pesc juz for the workmanship costs ur gonna save.
