I was looking for an Unlimited, but the price difference was past what I was willing to pay. You don't lose clearance, just longer wheel base.
If you do look for a Jeep JK, go for the 2012- present with the 3.6L. When Jeep launched the new "JK," it was paired with a 3.8L V6, that barely made over 200HP (THESE are the JKs that receive awful reviews). This new 3.6L makes 285HP, huge difference. Plenty of power for a small vehicle. I love mine. The only way I would ever buy a Wrangler was if they became a little more convenient. And with power locks, windows, interior lights, etc..., I was finally okay with getting one.
I have a 36 mile commute one way to work, ZERO highway, and 97% of the drive is under 40MPH. Little towns with stop lights, so some stop and go traffic as well. I'm averaging 20 MPG, and I don't think that's bad at all for a mostly "city" drive.
