Instruction

As you can see, the table car has 5 columns:

  1. vin – short for vehicle identification number
  2. brand
  3. model
  4. price
  5. production_year.

The names of the columns are at the top of the result.

There are 8 cars in our table: two Ford cars, one Toyota, three Volkswagens, one Fiat and one Opel. You can see that the price of a Toyota is $11,300 and the prices for Fords are $8,000 and $12,500. Note that the price for Opel is not specified – we'll explain that later.
