Yes, most reputable dealerships perform a service and inspection process on used cars before selling them, but the extent and quality of this work can vary significantly. This process, often called reconditioning, is a key factor that differentiates a dealership-bought used car from a private sale. The goal is to make the car safe, functional, and presentable to meet a certain standard. However, it's not a guarantee of perfection, and the level of reconditioning often depends on the car's initial condition and the dealer's policies.
A standard reconditioning process typically includes:
The table below outlines common reconditioning actions and their typical completion rates at franchised new car dealerships, which generally have higher standards than independent used car lots.
| Reconditioning Action | Typical Completion Rate at Franchised Dealers | Notes |
|---|---|---|
| Engine Oil & Filter Change | ~98% | Standard practice on nearly every vehicle. |
| Multi-Point Safety Inspection | ~95% | A standard procedure to identify issues. |
| Full Interior & Exterior Detailing | ~90% | Focus on presentation and hygiene. |
| Brake System Inspection/Pad Replacement | ~85% | Replaced if below minimum thickness. |
| Tire Replacement | ~70% | Replaced if tread depth is below 3/32 or 4/32 of an inch. |
| Battery Test/Replacement | ~65% | Replaced if it fails a load test. |
| Factory Recall Repairs | ~100% | Mandatory by law before sale. |
It's crucial to understand that reconditioning is not the same as a warranty. Always ask for a detailed report of what work was performed. For the highest level of assurance, look for Certified Pre-Owned (CPO) vehicles. These programs require cars to pass a rigorous, manufacturer-set inspection and often include an extended warranty.

From my experience buying my last truck, they definitely do some work, but you've got to check the details. My dealer gave me a printout showing they changed the oil, replaced the wiper blades, and detailed it. It looked great. But I still took it to my own mechanic for a pre-purchase inspection. He found a couple of minor things the dealer missed. So yes, they service them, but always get a second opinion for peace of mind.
