, Project statement
For this project, I was told to design a program for a car dealership that allows customers to
specify their vehicle and receive a quote. It should be form-based, allowing the user to input
their options using a mouse and keyboard. The program should also save the data that the
user enters, such as the user's name and phone number, and the date of when the form is
being filled in. It will consist of three forms: form 1 for options, form 2 for the summary and
price, and form 3 for the about us page. The VAT and monthly finance will be calculated
using formulas in the program and be displayed on from 2.
