This is an Easy to Follow Guide of all the Story Jobs that you'll encounter in Car Mechanic Simulator 2021 (The Blue Highlighted Jobs). Each job is broken down into the Car Being Repaired (Green), Engine of which you'll be working on (Blue), which Fluids you'll need to replace (Red), Which Tires and Rims you'll need (Yellow), Part to be replaced or Repaired (Orange), Any Body Repairs or Replacements (Purple) and finally the Paint needed for the car including the exact Paint Tyre and the numbers for said paint (Pink).

I have also added any Additional notes in White if there is something to be done before removing parts (for example; draining Coolant before removing a Radiator) to minimise any loss in CR.
