I stumbled across a great deal on a 4th Gen at CarMax for what that's worth (or so I think, it's being shipped now).

It was $10k less than anything similar that I could find elsewhere.

My wife has an ECO Diesel Jeep, and a tune transformed it.

Added 3+mpg and made it massively more responsive.

The exhaust brake is also a game changer in the mountains.

Her is fully intact and tuned for 50k miles with no issues.
