I have had this car for about 3 1/2 years now and I have not had any major problems. Very reliable and rugged vehicle. Excellent in the snow, dirt, mud. The rugged tires will get you out of any situation. Jump curbs, logs, boulders. Anything! Basically as far as off road capability you couldnt ask for anything more. The jeep is not a very great in the highway. Its noisy, rough ride (you will feel every bump), and will cost you a lot in gas. (be prepared for that)
Love the fact that I dont have to worry about the weather with this car. I know no matter what I will get to my destination. Taking the Top Off and driving it into city or the beach is best. You will definitely get lots of attention in this car.
Improving the ride (very rough on the highway and you will feel every bump),improve the interior, improve the gas mileage. ...but hey.... its a jeep!
