I was considering whether or not to move from my 96 RT/10 to an 03 SRT. My decision for now is to stay with the 96 RT since it doesn't have to be a daily driver. There is something more elemental, brutal, less refined about the Gen I and Gen II cars that appeals to the old time sport car buff in me, and makes me feel like I'm driving a Cobra, and not a C5 Vette.
After taking Skip Barber and doing Motocross in the SRTs, then driving home with no windows and no top on my 96 RT 10, I concluded that the SRT is a better daily driver, but that the RT/10 pushes more of my "sport car" buttons.
Only you can decide for you, which of the cars reaches further into your synapses, and sport car emotions. Whichever one calls out to you more is the one to keep.
I don't think you can go wrong either way.
