We designed the top without the "fake" scoop. Carbon fibre is cool enough by itself. But I prefer functionality over looks. The top is smoother, that means less wind noise and less aerodynamic drag. But after doing all this, adding a scoop to the top is plain easy. If you check my photo gallery, the car´s hood and rear wing was also done "in house".
The window switches are next to the shifter.
Seatbelts are "inboard", but because they are a 5 point setup. The original door mounted seatbelts don´t interfere with the window mechanism. As I said before, doors open with a remote control that releases the door latch. It can also be integrated to an alarm system. I didn't´t think of doing this to sell (there are only 8 Gen1 Vipers in Argentina), but more of for my own driving pleasure and being able to enjoy the car more often. I estimate that with 4.5K the whole thing (less the 2 window motors which are Neon or Ram motors)could be replicated. Maybe less if it´s more than one kit. This includes the Carbon Fibre top, the tempered glass windows, the window guides and lift system, left and right fiber glass templates to cut the top or the doors. The door "wing tips" which serve as a guide when the windows up. All the rubber and felt weatherstrip in order to seal everything. The RC door openers.
