looking at used JK's, educate me..

I own a lifted WJ, but I'm not too happy with it right now, so I'm looking to get into a used JKU. 07-09 are the years I'm currently looking at as they're in my price range, with anywhere from 30-60k miles. Are there any first year issues with the 07's? I'm also new to buying from dealers, what sort of factory warranty did JKs come with, and typically is it a good idea to get an extended warranty when buying a used one/is it even possible?

Check into the gears it has. I'd stay away from the 3.21s and look for 3.73s or 4.10s in the Rubis if you ever want to run larger than stock tires. If you're planning to go to anything over 33s, plan on regearing. Happy hunting!

In addition to the gear suggestions: if it shows any signs of having electrical "quirks" (e.g., wiper comes on by itself, even for a partial cycle), steer clear or insist that the seller guarantee the TIPM (Totally Integrated Power Module; aka the computer brains of the vehicle), for at least 6 months. I found a ground prob with mine, that I bought 2 weeks ago. If the ground fix doesn't work, I'm looking at a $900 part (TIPM's for other years are less, but why take the chance).

Yeah I heard 4.88 is good for 33s-35s? I've got 3.73s and 33s in my wj and its just fine. It'll be a couple months probably til I pick one up, I'm only 19 so I either I gotta get a cosigner, or wait a few more months til I have a total of 2 yrs of credit at my bank, or try a different bank..

I just purchased an 07 2 weeks ago with 49k miles. If you go 07 automatic it will have 4.10's unless the previous owner regeared it. Even with the 4.10's and 285/70/17's (basically 33's) it is still sluggish in OD unless you are going downhill. I drove it to Moab this weekend (4 hour each direction) and ran it without OD on the freeway 75% of the time. I bought an 07 because it is what I could afford. I will fix the troubles when they arise. I plan on keeping this thing for a long time to come. So far I am very happy with it.

As far as extended warranties go you will have to make up your own mind on that. Personally I don't ever buy them as I think they are overpriced. The only time in my life I ever bought one was on a TJ I had many years ago and when I blew the heads on it the warranty company denied my claim anyhow saying because I modified the vehicle they counted that as neglect? I had to take them to court to get them to pay. I haven't bought a warranty since.

So do more of the 07s come with 4.10 gears vs 3.73? (I thought that was just rubicons) I plan on either 285s if I don't regear, or 315s with a regear

Which gears will really depend on whether you get auto or manual tranny. I know that this comment applied to all vehicles, but it's an even bigger deal for 07-11 JK's. When Jeep moved to the Pentastar engine in 2012, they selected a much more appropriately geared automatic tranny. To get to the same engine to wheels gearing as a 2012 (i.e., same RPM for a given speed in top and bottom gears), a stock 07-11 would need to be regeared to 4.56. The gearing for the manual tranny is the same for all years.

Yeah I wish I could get a 12 or newer. My uncle has a 13 and it was faster stock than my v8 grand

All of the 07's with Automatics are 4.10's or so I have been told by members on this forum. Not sure about the standards. I verified through the dealer mine is 4.10.

I had to look this up, but you are correct, they did put 4.10's in the 07 automatics. Jeep needs to fire the moron who made the decision to move to 3.73 for automatics in 08-11.

hi, im not sure what used Jkus sale for in Utah but around here one with less than 100,000 miles are going for around $24-$27000. I paid about $27,000 for my 13 new. It is plain it has a/c hard top auto and 3.73's. So dont rule out new unless there alot cheaper. The stickers on most at the lots is way more but they can locate you a base pretty quick.

Atlanta is the same. If I could have gotten a Dark Cherry with auto and hard top, I would have bought new (color is discountinued for 2013 and none with in 500 miles had auto and hard top). The other point in favor of the 2013 is financing. As a rule you'll pay an interest rate 7% or more for an older JK (significantly more if your FICO score is under 700) and you'll be limited to 60 month financing. At the same time, you can usually get 72 month financing on a 2013, in the 3%-4% range (yeah, you pay an extra year, but you also get a new JK instead of one with 4-5 years of mileage on it).

I've found them around here for 22, 000 regularly with 40-70k miles, ideally I would just get a new one with a 72 month plan, but it totals to $350 a month with the options I want, I want a payment closer to $300 or even maybe a bit lower, but it's almost worth it to go new...

I got mine here in Utah for 21k with 49,000 miles on it. It is the most I wanted to spend on a vehicle so new was out of the question for me. I got 4% through the credit union and 72 months even though it is an 07. Credit Unions will work with you better than a bank. Also mine already had $600 worth of wheels on it, a Teraflex lift, brand new 35's (which I have since sold and put on 33's), and $700 worth of Bushwacker type fenders. It had auto, air, and a factory sub all of which I wanted. And it is super clean. These were all pluses as i would want to add all this stuff anyhow.

Dualtjs you said the dark cherry got discontinued , when did that start I got a dark cherry red one Saturday I was actually looking for a white one but they said they had this one and I thought well I haven't seen many that color running around my area so I bought it , seems like everyone is buying commando green I went to the store there where three in the parking lot , I was also looking at used and for about the same money I got the new one it made more sense to me
