Well, since I decided to kill the render, rather than run the risk of reaching retirement age before it died from natural causes, I have to say "Thank you" and that I am impressed with your dedication, although rather less with the way the car renders.    This has to be the only sports car going that has a bonnet seemingly composed of the same material as the windscreen (and a different material from all of the other bodywork).   Nevertheless, I have to stand corrected about "unrenderable".
