Nothing compares to the feeling of buying your first car, and this feeling is always to blame when people make poor decisions. Buying a vehicle is a complex and daunting task and should be approached with caution.
The first thing you must dwell upon is whether you want a new or used car. If you are buying a used car make sure you check the history of the car like the number of owners, previous mechanical issues or accidents because the price will largely depend on this. Car dealers will hide this information from you unless you explicitly ask them.
More importantly, you need to examine your budget and needs. It isn't practical to buy a sports car if you have a large family or dream about luxury cars when your budget can't support the price tag.
