Forza 2, What's a good V10 car?

I'm going to start the V10 tournament in a minute, and just wondering what are some good V10 and V12 cars. Forza 2, What's a good V10 car?
I'm too lazy to check if it's in Forza, but I would go with a BMW M6 or Lambo Gallardo in the real world. A new Audi S6 would also be a good choice, probably easier to drive thanks to 4WD(but slower). The only other V10 car I know of is a Viper, but those just suck if you need to turn at all...americans can't seem to make cars that do anything well besides having huge engines that let them accelerate fast in a straight line on smooth pavement.
