Andrew, I don't think it is abhorrent; however, it does have far too much Audi TT in the design and not enough iRobot concept car!
I saw the iRobot car at the Netherlands autoshow a few years back and it did look stunning in the metal.
The R8 is very colour sensitive (for instance, I can imagine it looking better in black - to hide those awful looking side vents); however, that is a sign of a poor design. Within reason, a car should look good in almost any colour <img src="/forums/images/graemlins/thumbsup.gif" alt="" />
