Buying a used car can save thousands, but only if you know what to look for. Even seasoned buyers overlook small issues that can turn into major expenses down the road.
To find out what commonly missed elements buyers should always check before purchasing a used car, GOBankingRates interviewed Lauren Fix, a nationally recognized automotive expert and founder of the Car Coach Reports, and Bryan Jewett, owner of Casey’s Automotive in Northern Virginia, who spent many years working as a technician, service advisor and service manager.
1. Title and Vehicle History
Fix recommended running a vehicle history report (like CarFax or AutoCheck) to uncover any accidents, title issues or odometer rollbacks in addition to what the seller tells the buyer.
Title issues a used car buyer might uncover, according to SlashGear, include:
- A salvage title explaining the vehicle was declared a total loss from either a flood, accident or other major damage.
- A rebuilt title showing a salvaged vehicle was repaired and inspected verifying the safety of the car to be driven again. Buyers should review complete repair history to see how much damage was done to the vehicle.
- If water or flood damage titles are found, then the buyer needs to get the car thoroughly checked out for mold, electrical damage, corrosion, rust, rotted seals, gaskets or bushings. Water damage can cause long-term issues that might not show up at first.
- Title washing is when a seller moves a vehicle to another state to clean up the title.
2. Service Records and Maintenance Proof
“A well-documented maintenance history is the best indicator of how a car was cared for, ” said Fix. “If records are missing, assume the work wasn’t done.”
Jewett recommended reviewing service records to check for regular maintenance like oil changes, brake jobs and factory-scheduled service, and confirming timing belt or chain replacements since neglect can lead to engine failure.
3. Electronic Systems and Warning Lights
Electrical repairs can add up fast, so checking everything including power windows, power seats, back-up cameras, entertainment systems, lights and all switches before buying a used car is best, explained Jewett.
Fix mentioned that since hidden electrical issues can be expensive and frustrating to repair, it’s best to turn on the ignition and make sure all warning lights are functioning correctly.
4. Fluid Leaks and Smells
“Check under the car and under the hood for oil, coolant and transmission fluid leaks,” said Jewett. “Even small leaks can become major repairs. Be aware of burning smells that can signal electrical issues, or musty smells that can signal mold or water damage.”
5. Tires and Brake Condition
Fix said that uneven tire wear or worn brakes may reveal suspension problems or neglect, and both are costly fixes that most buyers overlook.
Jewett suggested to try running a hand across a tire’s surface to see if one side is more worn than the other. This could signal the car needs alignment work or has underlying steering or even possible suspension damage.
6. Underbody Rust, Hidden Frame and Structural Damage
Even if a car looks great on the surface, past accidents can hide damage beneath the exterior. Asking for a Carfax vehicle history report and having a trusted mechanic inspect the car for signs of anything that could indicate poor repairs or compromised safety was recommended by Jewett.
Fix suggested checking underneath the car for rust, corrosion or any signs of frame repair. She explained these issues can seriously affect safety and long-term durability of the vehicle.
7. Inspection by a Certified Mechanic
Both Fix and Jewett agreed spending the money to have an ASE certified mechanic inspect the car thoroughly before making any offers on the vehicle is the best way to uncover issues that could lead to large repair bills later.
