A simple inspection step could save used car buyers thousands, but many drivers don’t even think to check it.
A viral TikTok from powertool1990 is gaining attention for breaking down what drivers should look for when buying a used car. In the video, the mechanic highlights key inspection points like suspension condition, test driving behavior, and overall vehicle feel. But one detail stands out: many buyers skip critical checks that could reveal hidden problems. For everyday drivers, this advice could mean the difference between a reliable purchase and a costly mistake.

In the video, powertool1990 focuses on practical, real-world inspection tips that go beyond surface-level checks. While many buyers pay attention to mileage and exterior condition, the mechanic emphasizes looking deeper, especially at how the car behaves during a test drive.
Suspension performance, unusual noises, and handling feel are all key indicators of a vehicle’s true condition. These factors can reveal issues that aren’t visible during a quick walkaround.
The One Detail Many Buyers Overlook
One of the biggest takeaways from the video is how often buyers skip checking the suspension system properly.
Problems in this area can include:
- Worn shocks or struts are affecting ride quality
- Loose or damaged components impacting steering
- Uneven tire wear signaling alignment issues
These issues might not seem obvious at first, but they can lead to expensive repairs shortly after purchase.
As we’ve covered before, hidden suspension problems are one of the most common issues in used cars
Why Test Driving Matters More Than You Think
A proper test drive is one of the most important steps when buying a used car. It allows you to feel how the vehicle performs in real conditions.
During a test drive, drivers should:
- Listen for clunks, rattles, or grinding sounds
- Pay attention to steering response and stability
- Test braking performance at different speeds
- Notice vibrations or pulling to one side
Skipping this step or rushing through it can mean missing serious warning signs.

Context & Why This Advice Matters
The used car market can be unpredictable, and not every issue is immediately visible. Many vehicles may look clean on the outside, but have underlying mechanical problems.
That’s why mechanic advice like this resonates with so many drivers. It focuses on real-world experience, the kind that helps buyers avoid common pitfalls.

The Bottom Line for Buyers
Buying a used car doesn’t have to be a gamble, but it does require attention to detail.
Take your time, inspect beyond the surface, and never skip a proper test drive.
Because the small things you check before buying can save you from big problems later.
