Kestrel Take
The car that started the pony-car craze and the most accessible American classic there is — the first-gen Mustang has bottomless parts support, a huge community, and simple mechanicals anyone can learn. Values are strong and stable. Rust and hack restorations are the risks; originality and a solid body drive value. A rust-free, honest '66 Mustang is a joy to own, easy to maintain, and a rock-solid collector buy. Inspect the body and floors above all.
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.
