Spoiler-light mode
Build the Satsuma and learn how the car works.
There is not one mandatory master sequence. The chassis and engine are separate workstreams you can tackle in either order. Each checklist item also includes a short explanation of what the real car part does, while gameplay help stays hidden behind Hint.
BUILD PATHS
How the workstreams come together
Prep is useful but does not block the build. Chassis and Engine can be worked on independently. The later rows show a simple first-timer route, not hard locks on every individual part.

After the build: safe first-start checks
This stays separate so the main checklist does not spoil later goals.
- Confirm oil, coolant, brake/clutch fluid and fuel are filled.
- Confirm spark plugs and oil filter are tightened.
- Check alternator belt tension before extended running.
- Do not ignore persistent metallic ticking, squealing or pinging.
