I am from Saudi Arabia and we have miles and miles of open straight highways to drive as fast as we want. I have done 300 Km/h run in a R8 before and its not as scary on 4 lane highways.
Plus how is $$$ related to hitting the top speed ?

Simply just all the extra weight of the GS. Remember the GS is the replacement for the base LS3 Z51's. They have the same horsepower but with all the goodies GM added to the GS it added weight and the wide body is less aerodynamic the then narrow body car. The power to weight ratio gives the advantage to the Base Z51. And even the old LS2 Z51's might give the GS a good run for the money being they were even lighter then the LS3 Z51's I think that match would be very close.

Which ever one is at the barber shop the day I get my hair cut.
But, if anyone is really serious about seeing who's got the fastest car, top end, then they should arrange to rent the private 8 mile oval test track in Ohio for a day. Get 100 people at $500 each to show up and we can see if their C6 GS can hit 185 MPH, their C6 LS2 can hit 186 MPH, their C6 LS3 and their C6 427 Convertible can hit 190 MPH and their C7 LT1 can hit 191 MPH(????)and their(my) C6 Z06 can hit 198 MPH and their C6 ZR1 can hit 205 MPH.
I'll be first in line with $500 for that fun filled day. But, if you can't afford to eat your car if you hit the wall, don't show up as your insurance carrier does not cover you when on the track.
Winner gets treated to a Happy Meal at McDonalds.

I always thought top speed didn't matter until I ended up in Germany with my C5. Then, top speed became a huge factor since I'm basically a very competitive driver. With mods, I saw my 02 at 183 and it had more, but that was enough to beat an AMG on the autobahn and a Ferrari 365GTB on the autostrada.
I know, very few will ever see top speed in their Vettes nor will they drive the autobahn, but there is a bragging factor in knowing that your car would walk away from a Porsche, or BMW at top end. Nah....it won't be the fastest, but it certainly won't be the slowest high American performance car.

The tires will determine if there is a limit. I highly doubt that will be the case, since top speed provides some bragging rights for a sports car (even if there is hardly anyone who comes close to reaching it).
The flat torque curve in the C7 should help the top speed. A peaky engine can have trouble getting up to speed unless the gearing is perfect, while the engine that pulls harder through the rev range can get to that sweet spot where max horsepower and top speed line up. The increased down force will likely provide more drag at high speed. You don't get down force for free, it increases the drag as well as the rolling resistance at speed. Gearing is also a big factor, but it's not likely that GM used top speed as the determining factor for picking ratios (if they did the car would top out right at the top of 7th gear, which it will surely not).
Will it be any faster than the C6, not likely (top speed for the C6 was typically listed at 190mph). But I bet it will be more comfortable at the limit, even though very few people will ever get there to experience it.

Even when top supposed top speeds are posted it will take a perfect storm to get there. Better yet has anyone on this forum taken a bone stock car to the suggested top speed of said vehicle? I know I haven't and I've tried.

With peak power being relatively very similar to the C6 I believe it will come down to drag/aero factors, and whether the C7 is truly more efficient in that regard, at that kind of speed, than the C6. Remember you need exponential-like increases in power to get relatively modest top speed gains the faster you go, as aero becomes the predominant factor to overcome.
I read somewhere that a Veyron is using 500hp to push through the air at 200mph. To get the next 50-60mph requires another 500hp.
As far as "marketing"; if it is faster than the base C6, they will list a number. If it is not, they will take the GS approach, and.. not list a number.
Why does it matter? Same reason any of the performance metrics matter, so we can bench race them on the internet of course.
