A limited has a few more options available: garage door opener, leather seats, tire pressure sensor, 240 watt sound system, satin door handles, fog lights, heated seats. The SRT6 has a few more on top of that. I've only had ours a couple of months and still discover new features all the time. It's a great little car - a little quirky sometimes. If you do your own service this site is invaluable. Good luck...Cam
