Parts are easily available.

Oil filter- <$10
Engine oil - similar to any Proton also can use
Gearbox oil - not sure
aircon compressor- <$200
brake pad-~ $60
engine mounting ~$300

I would say, if you service them outside...buy your own parts, it is a cheap car to maintain.

However, you might need to resolve all the necessary stuff like
engine mounting, brake pads, brake oil, engine oil/filter, air filter, tires, ...etc.

the first year, might need to iron out all this when you get used cars.
