I have been doing some reasearch of the above two motor vehicles and can't decide which I would prefer, despite the absence of the all new M6.

I have to admit, if it is the E63 M6, I would probably go with the Audi R8 (the V8 or the V10 model). But, what about the new upcoming M6?

Arguably, the R8 V10 would still be more expensive than the coming M6, but if you had a choice, which motor vehicle would you choose?

 

They are not comparable in any way, shape, or form. The R8 is beautiful, but very, very small. When you see it on the street, its stark as to how small and how low it is. The e63 M6 is much much larger as a GT, where the R8 is an exotic sized car. The next M6 is not in the running, imho, I cant take the engine and will never buy it. IF you want a small, sporty, near exotic, you go for the R8, but if you want an all around daily drive GT with a V10 screamer, you go for the M6
