2017 Jeep Wrangler JK Unlimited — Should You Buy One?

Typical asking price: $20,000–$32,000. There are 2 high-severity known issues you need to know before handing over a check.

Kestrel Take

The last year of the four-door JK before the JL redesign, and prices stay high because Wranglers refuse to depreciate. The 3.6L Pentastar is solid. As always with a Wrangler, the whole inspection is about how hard it was wheeled and the quality of any modifications.
