Thanks for all the great advise. I do live in VA and am keeping track of the days that my Viper in the shop for purposes of the Virginia Lemon Law and really appreciate the advise regarding documenting reoccurring problems as well as the heads-up on dealing with the "settlement facilitator." From my case research, it's my understanding that the buyback under VA Lemon Law actually covers money invested in the car, such as that spent on upgrades, assuming of course that they are not the cause of the problem, which they are not. My preference would still be not to have to force a buy back, but rather have the car working properly, since I actually want to own my Viper as modified. Still, if it comes to it, I will go down that road.
The body panel that fell off is that little triangle in front of the passenger door and inside the scallop (I think it's officially called the door hinge cover). It's held on with three screws that all came loose and fell off during the first 300 miles. Fortunately, I notice this panel was loose and actually caught it falling off when I was washing the car, so no damage was done. That was problem #1, and I'm still shaking my over that one. I check those screws all the time now.
