Buying a used car represents a major investment. Without knowing how the previous owner maintained and drove the vehicle, it’s impossible to tell what kind of mechanical issues might be lurking under the hood. That’s why a rigorous inspection process is absolutely essential before purchasing any pre-owned automobile.
However, inspections can vary dramatically in terms of quality and comprehensiveness. As a buyer, you want assurance that certain minimum standards are followed during the vehicle inspection process. This helps ensure critical components are not overlooked or missed entirely.
Below are insights into the key vehicle inspection standards consumers should understand and look for.
Seek Out ASE Certified Mechanics
One of the most important criteria is ensuring the inspection is done by an ASE certified mechanic. ASE stands for National Institute for Automotive Service Excellence. Technicians must pass thorough exams to earn ASE certification in a variety of specialties like engine repair, transmissions, brakes, electrical systems, and more.
Facilities that have ASE Master Certified technicians on staff are ideal choices to perform used car inspections. This level of ASE certification indicates high competency across all systems. It’s a marker of advanced training and qualification. Inspectors without proper ASE credentials often miss issues during the process.
Understand the Scope of a Comprehensive Inspection
A proper vehicle inspection goes far beyond kicking the tires or a quick drive around the block. At a minimum, the following components and systems should all be thoroughly examined:
- Engine, including compression tests
- Drivetrain and all fluids
- Transmission
- Suspension and steering mechanisms
- Brakes, brake lines, rotors and pads
- Electrical components and battery
- HVAC and emissions systems
- On-board diagnostics computers and error codes
The inspector should also do a complete test drive to check for any odd sounds, smells, or handling issues. The full inspection process generally takes 1-2 hours when properly and methodically conducted.
Demand a Written Report of Findings
Another hallmark of a quality inspection is the mechanic providing a comprehensive written report of their findings. This report essentially serves as a checklist documenting the condition of each system and component examined. It also includes photos of any problem areas found.
Having this level of documentation is crucial for the buyer’s protections. It provides proof of exactly what was covered during the vehicle inspection process. Any issues found are in writing, preventing disputes down the line over the vehicle’s condition at the time of sale.
Don’t Skip Your Own Test Drive
Even after an official inspection is completed, buyers should still take the vehicle for an extensive test drive themselves. Drive on highways, side streets, hills and try all driving modes. Be alert for any odd vibrations, noises, steering pulls, or weak acceleration. Essentially your test drive checks for drivability issues which complement the mechanical inspection.
Between your road test findings and the mechanic’s under-hood analysis, you get a complete snapshot of the vehicle’s true condition before purchase. The two processes together give you maximum protection.
Use Inspection Findings to Negotiate or Walk Away
The whole point of holding sellers to vehicle inspection standards is to gain leverage as a buyer prior to purchase. If issues are uncovered, use the inspection report to negotiate the price down accordingly. If repairs needed exceed your budget or comfort level, you also have the right to walk away from the deal altogether at this point.
When it comes to buying a safe car, always get price quotes on recommended repairs and verify they were completed properly before finalizing the transaction. This ensures you’re purchasing the vehicle as represented and prioritizing safety throughout the buying process.
Rigorous Inspections Protect Your Investment
Overall, a thoroughly performed vehicle inspection following industry standards is your best defense against buying a problem-plagued lemon. The small upfront investment in an inspection can prevent massive headaches and costs later on. By understanding the inspection process and insisting on quality, consumers give themselves the confidence to purchase pre-owned vehicles worry-free.
