The Vector W-8 production cars was closer to a concept car then production car. In an ideal world, they would have had more development before the W-8 production started. Since Vector had been claiming they would build cars for many years, they may have been under pressure to start building cars even though they needed more R& D on the car.
I do know the owner of the famous R&T cover car and he drives his W-8 all the time. Clearly a 911 Turbo or Acura NSX would make a better daily driver. I have yet to get feedback from owners of new lambos and Ferrari's on daily driving. I think some people would be shocked at how much headache some of the new exotics are.
