What should you check before buying a used semi truck?
The average used Class 8 truck in ACT Research’s June 2026 numbers had about 410,000 miles on it. At those miles, the records tell you more than the paint. Here’s the checklist I’d work through, what used sleepers are selling for this fall, and the exact limits for financing one with Five West.

How much is a used semi truck worth in 2026?
Late-model sleepers still bring real money, and older ones fall off fast. Here’s the market data through September 2026:
| Measure | Average | Month | Reported by |
|---|---|---|---|
| Used Class 8, retail (ACT Research) | $64,007 | September 2026 | TheTrucker.com |
| Used Class 8, retail (ACT Research) | $61,751; average miles 410,000 | June 2026 | Transport Topics |
| 2-year-old sleeper (Price Digests) | $92,330 | September 2026 | Trucks, Parts, Service |
| 5-year-old sleeper (Price Digests) | $52,430 | August 2026 | Overdrive |
| 10-year-old sleeper (Price Digests) | $25,390 | August 2026 | Overdrive |
Market averages reported in the trade press, checked October 29, 2026. J.D. Power had September retail prices down 0.5% from August and up 9.9% year over year.
Averages hide the spread, so here are specific trucks:
| Truck | Miles | Asking price | Listed by | Inside the over-the-road limits? |
|---|---|---|---|---|
| 2022 Freightliner Cascadia 126 sleeper | 447,786 | $82,900 | Yerevan Truck & Equipment Sales, Fontana, CA | Yes |
| 2022 Freightliner Cascadia 126 sleeper | 583,278 | $69,900 | Southport Truck Group, Tampa, FL | No, over 500,000 miles |
| 2021 Kenworth T680 sleeper | 466,376 | $48,100 | AAA Trucks, Monroe, GA | Yes |
| 2018 Freightliner Cascadia 125 sleeper | 678,151 | $30,100 | AAA Trucks, Monroe, GA | No, over 500,000 miles |
| 2016 Freightliner Cascadia 125 sleeper | 470,297 | $28,500 | AAA Trucks, Monroe, GA | Yes, inside 10 model years in 2026 |
| 2007 Kenworth W900 sleeper (engine rebuilt in 2020, per the listing) | 1,186,185 | $69,500 | The Wrays, Sawyer, KS | No, over both |
| 2016 Freightliner Cascadia 125 day cab | 477,800 | $21,700 | AAA Trucks, Monroe, GA | Day cab: standard rules, no age limit |

The two 2022 Cascadias ask $69,900 and $82,900, and the cheaper one is past 500,000 miles. J.D. Power’s Chris Visser said at an FTR conference in August that used sleepers were losing about 2% to 2.5% of their value a month.
How many miles is too much for a used semi truck?
No single cutoff applies to buying one. Visser said sleepers under roughly 400,000 to 450,000 miles stay attractive and values drop substantially above about 650,000. For financing, our over-the-road programs stop at 500,000 miles on the odometer.
Records count about as much as the miles. I’d take a 480,000-mile truck with full service records over a 380,000-mile truck with none. Just know a rebuild doesn’t reset the odometer: the 2007 W900 above had its engine rebuilt in 2020 and still sits outside both limits.
What should you check before buying a used semi truck?
Get these in hand before you agree on a price:
| Check | What to ask for |
|---|---|
| ECM report | Engine hours, idle time, fault codes, hard-brake events and time in each gear. Compare the hours with the odometer. |
| Overhaul history | Rebuild invoices with the date, the mileage and the shop. |
| DPF, EGR and DEF | Cleaning, replacement and repair records, plus any history of the truck going into derate. |
| Oil analysis | A fresh lab sample, checked for coolant, fuel and metal. |
| DOT annual inspection | The latest report. FMCSA requires an inspection at least once every 12 months, with documentation on the vehicle. |
| Tires and brakes | Tread at every position, linings, drums and air leaks. |
| Frame and fifth wheel | Cracks, weld repairs, fifth-wheel wear and the air bags. |
| Sleeper and APU | Heat, air, the bunk heater and APU hours. |
| Title and lien | The seller’s name on the title, any lienholder, and a VIN that matches the frame and the door label. |
| IRP plates and Form 2290 | Apportioned plates and cab cards are issued to the registrant’s fleet, so the seller’s plates don’t come with the truck. At a taxable gross weight of 55,000 pounds or more, file IRS Form 2290 and give your DMV the Schedule 1. |
If a seller won’t allow an ECM download or an oil sample, I’d walk.
What does a semi truck pre-purchase inspection cover?
It’s an inspection you pay for, at a shop you choose. Ask for a road test (loaded, if possible), the ECM download and fault codes, an oil sample sent to a lab, the aftertreatment system, and the brakes, tires, frame and suspension checked against the annual inspection items.
A short repair list is something to negotiate. A bad oil sample or a cracked frame is where I’d stop.
Is it safe to buy a semi truck for sale by owner?
It can be. An owner-operator or a small fleet can tell you exactly how a truck was run. No one handles the paperwork for you, so check:
- Names. The title should be in the name of the person or company selling.
- VIN. Read it off the frame and the door label.
- Payoff. If a lender’s on the title, get the payoff in writing from that lender.
- Money. Don’t wire anything early. When we finance a private sale, we pay the seller directly.
- Bill of sale. Have your attorney read it.
Our guide to buying equipment on Facebook Marketplace walks through more of the private-sale paperwork.
What are the age and mileage limits to finance a used semi truck?
For a used Class 8 over-the-road sleeper, the programs we place these deals with stop at 10 model years and 500,000 miles. Shop inside both and the program stays open. Those programs also look for:
- A personal guarantee. Over-the-road runs on a personal guarantee and is scored on the guarantor’s personal credit. There’s no corporate-only option.
- Comparable credit. A loan or lease the business has already carried and paid.
- Time in business. Most trucking programs prefer two or more years under the same entity.
- No leaseback. A sleeper can’t go on an equipment leaseback.
- Money down. Usually none with good credit and five or more years in business. Under five years, over-the-road sleepers and trailers usually put 5% to 10% down.
Day cabs and vocational trucks, like dump trucks and wreckers, run on our standard rules. They have no age limit, though an older truck can be tougher to get done.
Owner-operators adding a second or third truck are some of our strongest files. Try yours in the Quote Builder, which asks the truck’s age and odometer reading.
How does a private-party deal work with Five West?
A private seller doesn’t slow the deal down:
- Usually no down payment with good credit, private seller or not. The over-the-road exception above still applies, and startups and first-time owner-operators usually put some money down.
- Application-only decisions on qualifying files, with no tax returns or financial statements.
- Speed holds. The first response typically comes within 1 to 2 business hours. Clean application-only files can be approved in as little as 30 minutes, and funding can follow in as little as 24 to 48 hours after signing. The lien search and the inspection or appraisal ride in the same file.
- We pay the seller. If they still owe on the truck, we pay off that lender at closing, the lien is released, and the seller gets the rest.
- Soft costs. Delivery and an extended warranty can usually go in the same payment.
- Bundling. A tractor and a trailer can share one agreement, and the pair counts toward our usual $15,000 minimum.
Used trucks are underwritten on their remaining useful life at the end of the term, so older ones often get shorter terms. Our commercial truck financing page covers trailers, box trucks and fleets, and our equipment financing page explains the agreement.
What does a used semi truck cost per month?
For an established business on an equipment finance agreement with no money down, three example amounts come to:
| Example amount | 36 months | 48 months | 60 months |
|---|---|---|---|
| $48,000: about the 2021 T680 above | $1,526 | $1,194 | $996 |
| $75,000: between the 2022 Cascadias above | $2,385 | $1,866 | $1,557 |
| $90,000: near a 2-year-old sleeper’s average | $2,862 | $2,240 | $1,868 |
Estimated monthly payments for an established business (five or more years in business, good credit) with no money down. Examples, not quotes: actual payments depend on credit, the truck and the term, and older trucks may get shorter terms.
Stretching from 36 to 60 months takes the $75,000 example from about $2,385 to $1,557, but you’ll pay more in total. Match the term to how long you’ll run the truck, and ask your CPA how Section 179 applies.
Can a startup or first-time owner-operator finance a used semi?
Case by case, and I’d rather be plain about what it takes. A first-time owner-operator is underwritten as a startup: personal credit typically 700 or higher, provable time behind the wheel, working capital left after the purchase, and usually some money down.
On an over-the-road sleeper, the programs we place these deals with look for two or more years in business and credit the business has already carried. A business that has never had a loan or lease gives them nothing to compare against yet. Day cabs and vocational trucks run on our standard startup rules.
Send us the file before you put a deposit on a truck, and we’ll tell you what it needs. Our startup equipment financing guide covers the rest.
