Test drive a car before buying it. Test drive the vehicle you have chosen before beginning negotiations. No amount of prior research can compete with first hand experience. You may find yourself unpleasantly surprised by a rough ride or coarse handling.
Although some sites suggested not test driving a vehicle because of the emotional attachment that can happen, it is never a good idea to purchase something without trying it out. Take at least a fifteen minute long test drive to really get a feel for how the car handles and how comfortable the car truly is.
