I pick up my new 2013 Unlimited on Saturday to use as my daily driver. I already have a built TJ, so the question is now how long I can keep my hands off of the new JKU. I have a hard time letting any of my cars/Jeeps stay stock for very long. Temptation...
I had a '99 TJ to start. It was built nice, but you all know, it's never really "finished". We then got a 2010 JKUR new. I was with the group of pre-JK owners that laughed and poked fun at the JK's. Then in 2010, my "better" (?) half said "you know, if I had my own Jeep, I could do my own trails at EJS. I found that as a challenge, and we went to go test drive one. WOW. Later that day, we owned a new JKUR. I started building on it, then realized that time and money wouldn't allow for 2 builds at the same time. So, I sold the TJ on base, used the money to build up the 2010 and the extra money to by an R6 (another story for another board). I can say that after putting 35's on it with an automatic, you learned to mash harder on the gas pedal to get it moving--especially living at 5k feet above sea level. I was planning on a re-gear to 5.13's, and it needed new ball joints and beefier steering components. Then I saw this "Anvil" color for 2013 on the 10th Anniversary edition, went to go see it in person, ended up trading the 2010 for it.
Anyways, to the OP, it's your call. I can say that I'm MUCH happier with the 2013 than the 2010, granted we've only had it for less than 2 weeks, and only have 400 miles on it. I want to say Chrysler has addressed the head issue (my build date was May 2013). But from what most have said, they noticed a "tick" at the dealership before they signed the paper (and yes, I know others have said it presented itself later down the road). I listened to ours after the test drive, and it was so dang quiet, you could barely tell it was running. So, we decided to get it (crossing fingers). The power/transmission difference alone was worth it--under moderate throttle, it feels great to have the front end lift up a bit... a feeling I've missed (plus on the 10A, it already comes with AEV bumpers, MetalCraft/AEV functional heat reduction hood, trans cooler (standard on automatics, I think), rail/tube sliders, and functional steel "skid" for an air dam (instead of the flimsy plastic).
