The initial model had a problem with the headers, which the manufacturer later replaced. I did my own with a Borla. This is the most reliable car that I have ever owned. Other than the header, it has never needed service (now has 60,000 mi., 11/05). After market upgrades are fun, and very worthwhile. Is very easy to self service. I wish that a diesel conversion was available! I have always wondered why the ratings have never been higher, except that everyone wants "fast and furious", (low end disposa-cars), instead of powerful, durable, rugged, and dependable. GO JEEP :)
Aftermarket upgrades - brush guards, front and rear - lift kits - wider flares - off road lights - replacement bumpers - tops! etc.
