I must specify the color, year, mileage of the car. Only years from 1980 and above can be specified. I can optionally specify a description of the car. If I enter all of the required information in the required format, the car is recorded. If I do not specify all of the required information in the required formats, the car is not recorded and I am presented with errors. Upon successfully creating a car, I am redirected so that I can create another car.
