Saving up for a used car can be quite difficult, especially if you are already stretched to the limit and do not have much money left over after every pay check to put into savings. The length of time you will spend saving up for a used car will depend on how much you want to spend on a vehicle and how much you can save every month. If you are looking at buying one of the best used cars under 5000 dollars but can only save a hundred dollars a month it could take you over four years to save up enough money for a vehicle. Of course, when you are saving up money you should also keep in mind that something could happen that requires you to spend your savings, such as a broken washing machine or necessary home repairs. Saving up money is always easier if you can reduce your monthly expense so you can put more into savings.
