You want a C7 Grand Sport. They will make one in a couple more years I'm sure. No one really wants a narrow body vette, but they will buy them when it is the only option. Then they will trade it in for a new one with the big tires and fenders in 2-3 years. How many 2010-2013 standard Vettes have you seen on the road? I've seen 5-10 since the GS came out. I see GS Vettes everywhere.
Your option now is a C7 z51.. That's a pretty damn good car option. Bigger brakes, dry sump, shorter gearing, stiffer suspension..
