I got my 06 Grand Cherokee 5.7L Limited at almost the same time Jason got his TBSS. The build quality on my Jeep is better, its had less problems, nicer interior, more comfortable, higher tow rating, slightly better fuel mileage, and off the line we were side by side. He didn't start to pull on me until about 40mph. Needless to say, he was happy to get rid of his TBSS and I'm happy to keep my GC for a couple more years.
