1966 Ford F-100 — Should You Buy One?

Typical asking price: $12,000–$38,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

A gorgeous, simple, endlessly customizable classic pickup that has ridden the vintage-truck wave upward. The FE and inline-six engines are durable and swaps are common. As always with old trucks, the cab and its mounts are the whole ballgame.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
