I think full service at Perodua for few hundred bucks including materials is reasonable and surely all original parts guaranteed.
For me I DIY a few things and let Perodua do up the rest which I don't want to do.
DIY myself.
1) Replace brake fluid annually (I use Bosch DOT4) I believe the original was DOT 4 and not DOT 3 judging from yellow color. I do NOT bleed brake fluid, I replace by pumping everything out at 4 sides.
2) Replace air filter. Buy outside original at RM18 only.
3) Replace with Toyota Long Life Coolant, RM20/bottle. every 2-3 years replace.
4) Replace spark plugs at 25k KM, check and re-gap at 10k. Buy NGK outside RM37 only.
5) Service and inspect the front and rear brakes. Mine still ok.
6) Already due - replace power steering fluid. They use ordinary ATF Dexron 3. Easy, Suck out from bottle and replace new, do it twice.
I instruct Perodua only to replace oil and AT oil (when necessary) and whatever their 10-20 point check.

Actually all these jobs can be learnt and done by anyone physically fit. I'm approaching 60 and I'm still at it. In those days, some of the above jobs were detailed out in owner's manual. Common sense tell you if its detailed out in manual, with the right tools, any owner can do it. Now there's Youtube, look up some maintenance jobs and learn from there. Don't say dunno how to do or its blardi filthy job.

Trust me, its all the same procedure for those jobs.
During my time, Castrol GTX was only RM17. Mobil 1 just entered the market at about RM60 something. Spark plugs were RM2.50 each.
As for common type spark plugs, they remain exactly the same engineering design except for sized down. Cost reduction, that's all, nothing improved.
There's no harm done to replace the oil yourself. I used to drain the oil when back from work and let it drain to next morning, just install new filter, plug the sump, fill in new oil, go to work. 5 minutes job.
