hopefully not very similar. The 599 was a beautiful car but had very standard proportions and was not exotic looking. The new F12 looks like a confused out of wedlock child of 599-California parents. The GTS Viper (IN IT"S PRIME, the looks is dated now) was a much more exotic looking car than the 599 was and the F12 will be. The F cars mentioned here are rectangles with a few lines.
