Porsche, but that's the obvious one. As far as cars from manufacturers that are already in the game, there should've been more Ferraris - at least the F430, F40, 599, California, and 512BB since they were in GT5P. I was also disappointed to see few new race cars outside of the R8 LMS and Mazda Furai. Since they were featured so heavily in the trailers for GT5 I was expecting some new WRC cars (Ford Focus, Citroen C4, Subaru Impreza), Super GT cars (Nissan GT-R, Lexus SC430) and Le Mans prototypes (like the Audi R10).
