what happens if id === 0? or id === -2?
you could refine this if statement a bit to cover more of these edge cases.
if (id < 1)
| return inventory[inventory.length - 1]; | ||
| } else { | ||
| for (let i = 0; i < inventory.length; i++) { | ||
| if (Object.values(inventory[i])[0] === id) { |

you're getting the job done, but there is a more direct way to get at this information.
if (inventory[i].id === id)
| const car33 = getCar(33); | ||
| console.log( | ||
| `Car 33 is a ${car33.car_year} ${car33.car_make} ${car33.car_model}` | ||
| ); |

great job solving this first challenge. writing a function is perfect way to make your code reusable.
| let lastCar = getCar(-1); | ||
| console.log( | ||
| `Last car is a ${lastCar.car_year} ${lastCar.car_make} ${lastCar.car_model}` | ||
| ); |

ah, now i understand why you wrote that if statement on LINE 78. great job using your function to solve both of these challenges.

wow. constructing this sort function from scratch is an impressive bit of work. for future reference: JavaScript includes a built-in sort method for arrays which performs a similar logic with a slightly different syntax.

| let oldCars = []; | ||
| console.log(); | ||
| // let oldCars = carYears.filter() | ||
| console.log(carYears.filter( car_year => car_year < 2000).length); |

perfect way to solve this in one line.

| let BMWAndAudi = inventory.filter(inventory => inventory.car_make === "BMW" || inventory.car_make === "Audi"); |

another perfect one-liner.
| console.log(parent.child.age); | ||
|
|
||
| // Log the name and age of the grandchild | ||
| console.log(parent.child.child.name + ", " + parent.child.child.age); |

this could also be written as a template literal using backticks and interpolated strings.
console.log(`${parent.child.child.name}, ${parent.child.child.age}`);
