2020 Ford F-350 Power Stroke — Should You Buy One?

Typical asking price: $42,000–$60,000. There are 3 high-severity known issues you need to know before handing over a check.

Kestrel Take

A one-ton workhorse — the F-350 with the 6.7L Power Stroke and the strong 10-speed automatic delivers massive tow and payload capability with modern refinement. As with any HD diesel, the value hinges on emissions-system health, whether it was deleted/tuned, and how hard it was worked. A documented, stock, un-abused dually or SRW F-350 is a hugely capable truck; verify the diesel's history in detail.
