The safest early economy is conservative. Credits have several competing uses — cars, facility unlocks, Workshop levels and cosmetic Furniture— so spending the opening balance on a second car simply because it becomes affordable can slow down the systems that improve the whole garage.
- Keep the first car stock while it is still winning comfortably.
- Buy functional facilities before cosmetic Car Park finishes or Furniture.
- Use Engineers to strengthen race income before investing in bonuses that need a large garage to scale.
- Upgrade the first car when difficulty actually rises, rather than pre-emptively spending materials.
- Favor Workshop structure when you want a permanent garage-wide benefit; buy car-specific parts when the current vehicle needs immediate performance.
