2007 Jeep Wrangler Unlimited Sahara 4dr SUV (3.8L 6cyl 6M)
I had bought the 4 dr automatic Sahara, JK with the hard/soft combo top in 2007. Loved it at first; but when the transmission started slipping driving through town at 45mph; not once, but twice. No dash or computer error, and the dealer couldn't find a cause/problem. Traded it for a 2007 GMC 2500HD. Nuff said. I got 24 mph on the hwy, but I had made some changes to get that mileage.
Fix the da... transmissions, and completely paint the roll bar.
