Buying a used semi-truck is a big investment. Whether you’re a first-time buyer or adding to your fleet, you know the requirements: find the right truck that meets your needs and fits your budget. But how do you sort through the ads and spot the real deals? It’s all about reading between the lines. Here’s what you need to know:

Beware of Vague Descriptions

If an ad only says "Runs great!" or "Low miles!" without much detail, it's time to dig deeper. Vague descriptions hide a lot. Sure, "low miles" sounds good, but are those highway miles or stop-and-go city driving? "Runs great" is great… until it’s not. If the seller isn't upfront about key details, make sure you ask. Transparency is key in any truck purchase, and the best sellers provide a full, detailed history of the vehicle, including maintenance records and previous use.

Watch for Buzzwords

When you see words like "well-maintained," "fleet-owned," or "one-owner," pay attention—but don’t stop there. Ask for the proof. “Fleet-owned” can mean regular maintenance schedules, but it can also mean heavy usage. Similarly, “well-maintained” is subjective and can vary from one seller to another. Look for documentation that backs up these claims, and always request to see service records. It’s fine for sellers to throw out buzzwords, but it’s up to you to verify their veracity.

Pricing That’s Too Good to Be True

A suspiciously low price should make you pause. Sure, everyone loves a deal, but if the price seems too good to be true, there’s likely a reason. It might be masking mechanical issues, hidden damage, or an extensive repair history. On the flip side, don’t assume a high price means high quality. Check market prices for the model you’re interested in to ensure you're not overpaying.

Mileage: The Bigger Picture

Mileage is one of the first things you’ll look at, but it’s not the whole story. High mileage might not be a dealbreaker if the truck has been well cared for, and low mileage doesn’t always guarantee the truck is in perfect condition. Always consider how the truck has been used and maintained, and take the vehicle’s overall condition into account.

Be Smart

Reading between the lines of used semi-truck ads means paying attention to what’s said—and what’s not. Ask the right questions, dig for the details, and always trust your gut. Finding the right truck is about more than just scanning listings; it’s about seeing the bigger picture behind the ad.
