The transfer case blew up, and I could not shift into 4-wheel drive. I brought it to the dealer, and they fixed it free of charge.
They also recalled the vehicle because there was ignition problems on all 2001 models. Again, they replaced it, free of charge.
Do not buy any optional package. I made this mistake and I bought the jeep with the larger canyon tires, the CD player and overhead sound-bars. After a few months, I started to dislike the sound system. So I ended up buying a sub-woofer, amp, made my own custom box, a Kenwood receiver, and 5" speakers. In short, I bought a brand new sound system. You would also want to buy new tires and rims. Although I am content with my canyon tires, many would prefer larger tires. Personally, I am scared of the "center of gravity" issue.
The engine runs great. Many made fun of my Jeep saying that it could not handle the highway. Although it was kind of noisy inside, especially with the soft top, if ran fine. In fact, they could hardly keep up with me! In the streets, the pick up is perfect and powerful. But of course, it depends on how you shift.
The perfect thing about the Jeep is its road capabilities. Even though I don't do much off-roading, I do enough during winter. On the year that I bought it, it snowed about 15". Guess what... My jeep was the only automobile in the streets. Of course nobody was crazy enough to drive that day, but that's what's great about a Wrangler- you can go crazy! The 4-wheel drive stuck to the road like a thong on a 400-pound fat guy. The following year, it snowed again, and all you can see on the road are my tire marks.
The Jeep Wrangler is awesome! Since I bought it in yellow, I've had so many compliments and head-turnings. You can fix it up really nice, but of course it will cost money. My next project is replacing the exhaust system and adding tubular bumpers.
