The most important point to note is that you should first find out as much as possible about the advertised vehicle and the seller before making an appointment. To do this, you should ask the seller on the phone about each item in the car ad. You can find used cars for sale online and an overview of vehicle abbreviations in car ads online. If the seller cannot be reached by phone, you can also clarify some questions by email first. However, you can always hear more from the spoken answer on the phone than from an e-mail. What do you think about this?
