Car servicing is basically changing of engine oil and oil filter plus checking or changing (if necessary) of brake pads, belts, battery, tyres rotation, coolant and other oil, etc. Any workshop also can do.
The only difficult one is maybe changing of the spark plugs (every 100,000km). That may require more specialised workshop.
I did my 90k servicing with my own engine oil at outside workshop. I only paid $30 nia. Car is running just as good, nothing wrong wat. Important thing is to use good engine oil for which I'm very particular and willing to spend.
Only major servicings (every 40k) and my next servicing at 100k (because of changing spark plugs), I may go to Autosaver. I don't believe in servicing at TC. They are so expensive and what they do or didn't do we also don't know. We only send in the car and collect later. At outside workshops, we can stand there and watch everything they do (if we want) and it's so much cheaper.
