Used 2021 Ford F-350 Super Duty for SaleNationwide

How much does the 2021 Ford F-350 Super Duty cost?

Prices have softened 1.43% compared to this time last year, making it a favorable time to shop this model year.

There are 2,057 listings available, which gives you a solid amount of inventory to compare.

Is the 2021 Ford F-350 Super Duty a good car?

Generally — the 2021 Ford F-350 Super Duty earns a 4.4/5 user rating and a 7.7/10 expert rating. The model scores 9/10 across Look and feel and Form and function.

Owners consistently praise its robust performance, spacious interior, and the amount of features you get for the price. The review summary also points to strong fuel efficiency on long trips, which adds to its appeal for buyers who spend real time behind the wheel.

The trade-offs are clear: the expert review calls out poor ride quality, poor handling, and noise. That means it makes the most sense if you need a heavy-duty truck for serious towing and hauling rather than a relaxed daily driver.

For shoppers who want maximum capability and a wide range of configurations, the overview frames it as a compelling choice. With 33.7% of listings marked as good or great deals, the market still gives you room to shop carefully.

Is the 2021 Ford F-350 Super Duty reliable?

Owners rate it 4.4/5, a solid signal of long-term satisfaction.

The owner summary points to a truck that feels robust and dependable in everyday use, with many drivers describing it as a strong performer that delivers a lot of features for the money. That kind of feedback matters when you’re looking for a heavy-duty truck you can count on over time.

The expert review also reinforces that sense of durability by describing the diesel powertrain as effortlessly motivating the truck and delivering on its promise when hauling. The cost-effectiveness notes add that it is a sensible buy when you need it for towing and hauling, which supports the case for long-term ownership.

For used buyers, the main risk is less about basic toughness and more about whether the truck was used hard, so condition and maintenance history matter a lot.

What should I look for when buying a used 2021 Ford F-350 Super Duty?

Accident-free inventory is solid at 80.4% — always verify the vehicle history report.

You should still check the vehicle history report carefully, because heavy-duty trucks are often worked hard and may have seen towing, hauling, or fleet use. A thorough inspection should focus on wear items, signs of heavy-duty use, and whether the truck’s condition matches its mileage and price.

Pay extra attention to how the truck was equipped, since the F-350’s appeal changes a lot by trim and configuration. You’ll also want to confirm that the features you care about are actually present, especially on lower-spec examples.

Key things to evaluate:

• Trim level: The F-350 comes in XL, XLT, Lariat, King Ranch, Platinum, and Limited trim levels. The cabin is more purposeful in the Lariat and below, while King Ranch and above move into higher-end décor and more luxury-oriented presentation. Base-trim trucks are more work-focused, so check carefully for the comfort and convenience features you want.
• Powertrain: The truck offers multiple powertrain options, including an available turbodiesel V8 that delivers huge torque and strong towing ability. The expert review also notes that the diesel and 10-speed automatic work well together when hauling.
• Safety package: Available driver-assistance systems include adaptive cruise control, forward-collision warning, automatic emergency braking, lane-departure warning, lane-keep assist, blind-spot monitoring with trailer coverage, and rear cross-traffic alert. Adaptive cruise control does not bring the truck to a full stop, and blind-spot monitoring still requires careful mirror adjustment.
• Infotainment: The truck uses an 8-inch touchscreen with Sync 3. It includes smartphone integration, wireless smartphone charging, navigation, FordPass Connect services with a 4G LTE WiFi hotspot, and a B&O premium sound system. The screen is small by current standards, and the system can occasionally hang or ignore inputs.
• Fuel efficiency: The expert review reports 15.4 mpg on an unloaded test loop and 16.5 mpg over a week of mixed driving with the diesel powertrain.

Which 2021 Ford F-350 Super Duty trim should I buy?

The 2021 Ford F-350 Super Duty is offered in 6 trim levels: XL, XLT, Lariat, King Ranch, Platinum, Limited.

Here's the short version:

• XL: This is the most work-focused choice, so it makes sense if you want the truck’s core capability without paying for luxury touches. It is also one of the trims where adaptive steering is not available.
• XLT: This is the sensible step up if you want a better balance of equipment and value while staying on the practical side of the lineup. It still keeps the truck’s purpose-first character.
• Lariat: This is the best-value trim for many shoppers because it starts bringing in a more comfortable, better-equipped cabin without jumping all the way to luxury pricing.
• King Ranch: This trim is where the cabin starts moving into higher-end décor, so it suits you if you want a more upscale truck feel while still keeping heavy-duty capability.
• Platinum: Choose this if you want a more premium presentation and more of the truck’s upscale equipment without going all the way to the top trim.
• Limited: This is the luxury-oriented pick, with plush leather, a high-end audio system, a panoramic glass sunroof, and the available turbodiesel V8 and 4WD. It is the right choice if you want the most upscale version of the F-350.

Adaptive steering is standard on Limited and optional on other trims except XL and XLT.

Is now a good time to buy a used 2021 Ford F-350 Super Duty?

This is a moderate market for selective buyers, so it pays to compare listings carefully and move quickly on strong examples.

• Deal availability: 33.7% of listings are priced as good or great deals.
• Inventory: There are 2,057 listings available.
• Price trend: Prices have softened 1.43% compared with last year.
• Clean inventory: 80.4% of listings are accident-free.

If you find a listing below $48,719, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Ford F-350 Super Duty's resale value?

The current average of $49,870 sits slightly below last year's $50,593.

That kind of price movement suggests the truck has held value reasonably well, even with a modest year-over-year decline. For a future seller, that means demand is still anchored by the F-350’s capability and broad appeal among heavy-duty truck shoppers.

Because the market is still pricing this model near the middle of its annual range, condition and equipment will matter a lot when it comes time to resell. Well-kept trucks with the right configuration should remain easier to move than rough examples.

Vehicles with solid owner satisfaction ratings, like this model year's 4.4/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Ford F-350 Super Duty safe?

The 2021 Ford F-350 Super Duty does not have official crash-test data available, so you should lean heavily on its driver-assistance equipment and the truck’s size when evaluating safety.

It earns a 7/10 safety score from our experts.

Available driver-assistance systems include adaptive cruise control, forward-collision warning, automatic emergency braking, lane-departure warning, lane-keep assist, blind-spot monitoring with trailer coverage, and rear cross-traffic alert. The review notes that adaptive cruise control can behave unevenly in traffic and does not bring the truck to a full stop, while blind-spot monitoring still requires careful mirror setup.

The review also points out that the truck’s size and weight can work in your favor in collisions with smaller vehicles, but that same mass means you should be especially attentive around other road users. For used buyers, that makes a complete safety-system check and a careful test drive especially important.

Should I buy a 2021 Ford F-350 Super Duty or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 33.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 80.4% — always verify the vehicle history report.
• Price trend: Prices have softened 1.43% compared with last year.
• Owners rate it 4.4/5 — a solid satisfaction signal.
• The 2021 adds adaptive steering on Limited trim and expands the lineup’s mix of capability and technology.

Consider the 2020 if:

• At $45,720, the 2020 costs less than the current year's $49,870 average.
• It adds a new 7.3-liter V8 and a Tremor off-road-inspired trim.

The bottom line: If you want the stronger current-market mix of inventory, pricing, and updated equipment, the 2021 is the better all-around pick. If your priority is spending less up front and you still want broad capability, the 2020 is the more budget-friendly path.
