'97 993TT, '14 E63 S-line, '17 GT-R and a couple of '12 Mini Cooper S Countryman ALL4s for the kids.
Meh. 0-60 this, lap-time that. They are both fantastic cars that demand respect.
I don't plan on buying either, but if I had to choose I'd probably pick the RS7. The interior is to die for. That's what I'll be surrounded by when I'm driving. I personally like the exterior but I get that this car is either love/hate. It'll still beat the snot out of just about everything else out there. The Porsche is definitely better qualified on a track, but I doubt that this is an important criteria for 99% of buyers of either car.
And yes, the body roll needs to be addressed. It looks like an old fiat without antiroll bars coming around the corner loaded down.
