What is wrong with Viper's structural design?

The biggest problem is of course the frame.  It is ancient, mildly put and it is deficient in providing bending and torsional rigidity.  This frame belongs on a home made kit car, not on a car that is being advertised as world class performer.  I was looking for the front posts to create a brace through dashboard reinforcement and windshield frame but I could not find any.  Am I blind here?  Oh and where did the rear cradle go?  It was missing on the previous generation and it is still missing on the new car. 

If GM got this part, why cannot Fiat and Gilles get this through their skulls?  Still looking for those improvements on the new Viper.  If anyone knows, I would like to hear about it.

What really puzzles me here is the fact the new Viper starts out as a coupe, is Fiat really that cheap and Gilles that dumb to create at least interior cage, using a roof structure?  Light alloys are available and for the money Viper costs, it really should have one, just like it should have a better front cradle and rear cradle actually there.
