Buying and Maintaining a Car Buying a car – whether new or used – is one of the biggest purchases we make. It is important to take your time in deciding which car to buy and not be pressured by anyone who simply wants your money or your signature on a contract. Once you decide on the vehicle that best fits your needs and budget, shop around for the best price, know the vehicle’s history (if used), and be prepared to walk away from the deal if your questions are not being answered.
