2007 Audi S8 quattro 4dr Sedan AWD (5.2L 10cyl 6A)
My decision was between a Mercedes S550 4 matic sport and the Audi S8. The S550 is nice, but the S8 just felt like something more special. The v10 engine (smooth and quiet at normal speeds, and unbelievably poweful and "baritone" when you want it to be), and the special "S" interior and exterior felt like something a step above the norm. Even the ride (with the std 20 inch rims) is wonderful in comfort mode... unbelievable given the potholes in my part of the country). I average about 15.5 mpg (70% city/30% highway). Not great, but hey, that v10 power/noise has got to come from somewhere. Net, no regrets so far.
