2018 Porsche 718 Cayman — Should You Buy One?

Typical asking price: $48,000–$68,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

One of the best-handling cars at any price — the mid-engine 718 Cayman is a precision instrument, and the turbo flat-four (while less charismatic than the old flat-six) is quick and efficient. It's a Porsche, so service is pricey and full history is essential. A stock, un-tracked, documented Cayman is a superb, usable sports car that holds value; verify the PDK/manual health, service records, and that it wasn't a track toy.

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.
