No cruise.
No steering wheel radio controls.
The car's already become too Vette looking on the outside. My initial thought is to try to keep gadgetry to a functional/safety/performance level. (Still perplexed at the idea of the vertical stack of gauges)
On the other hand some useful improvements: Bring back adjustable lumbar (guess I won't start my hunt under the seat wondering where the inflation bulb is), shorten the too-easy-to-accidentally-activate wiper stalk, delete the gas cap tether, and, if you bother to put a radio in the car, please include better speakers and a cleaner sounding radio head unit (note to Russ--my SRT's overall sound system is better than my GTS' but I agree, the SRT's mid range is very weak. Also, the bass doesn't cause any vibration in my car but, like XM's satellite system in my SUV, the low end suffers from awful, muddy, probably intentional coloration--likely some non-music oriented marketing person trying to please 17 year old Joe Bazooka-head who never has heard live music and somehow thinks nasty booming thumping is accurate sound reproduction. (Kudos to Lexus for making a strong effort with the Mark Levinson sound series...not that an ML system should ever be considered for a Viper.) Whoah, I'm almost officially off topic...so, let me add on a more important positive note, THANK YOU Dodge for the incredible handling and braking you've bestowed on our SRT beasts!
