As long as you did not sign any agreement papers with the car dealerships, you are under no obligation to buy a car from them. However, if you did, not buying can be tricky as you may have to pay the penalty mentioned in the contract. The best way to avoid such a conflict is to take your time exploring the car in the mall. If you decide to buy it, book an appointment with the dealership instead of signing a legal contract. That way, you will have more time to think and can save yourself from impulsive buying.
