To avoid being ripped off when buying a used car from a dealer, follow these guidelines:
1. Research the car's market value and set a budget.
2. Get a vehicle history report and have the car inspected by a trusted mechanic.
3. Test-drive the car and pay attention to any strange noises or issues.
4. Negotiate the price and review all paperwork carefully before signing anything.
5. Consider purchasing from reputable dealers or using a certified pre-owned program.
