I have seen many instances where the parents have bought a car for their child and have ended up with a dead or disabled child. This happens because the child was not treating the car with respect for how dangerous a car can be. At a young age, teens can think that they can get away with many things, and they do. If you purchase the car yourself, you will respect it more, and are less likely to take chances with it. There may be a good reason that I will not let you borrow my car.
Lies cause more problems than the truth.
If you look around hard enough I am sure that you may be able to find a job within walking distance of your home. I know of many adults that have walked over two miles each way from their home to their job each day. I know of at least one adult that walked from Smyrna to Tucker Georgia each way to work for over fifteen years. I encourage you to look this up if you do not believe me. Quit using the poor excuse that you must have access to a car before you can get a job.
