Challenge FAQ

Auto repair garage simulator challenge modes

What changes in Easy, Standard, and Hard?

Easy lowers the net-worth goal and gives demand/cost help. Standard keeps the normal model. Hard starts with less cash, higher costs, weaker demand, and a higher target.

Where is my personal best saved?

Your best result is saved only in this browser using localStorage. There are no accounts or server saves.

What decisions matter most?

Watch diagnostic time, parts margin, mechanic staffing, bay capacity, comeback repairs, trust, and cash before adding bays or promotions.

Can I download my auto repair results?

Yes. The results screen can create a local CSV with completed monthly evidence and the current partial month. It includes operating settings, mechanic staffing, repair demand, jobs completed, lost jobs, diagnostic time, repair quality, parts inventory, comeback risk, costs, profit, cash, and net worth, and nothing is uploaded.

Keep learning Test your assumptions with our interactive tools: quantify margins in the Mechanic Labor Productivity Lab or model operational bottlenecks in the FMEA Risk & Quality Lab.
