The Aura pricing I found to average approx. $2,000 to $2500 higher than the Milan, with the features I wanted.
Less leg room than the Milan and I had less headroom because of the installed sunroof.
The Aura had less rear headroom. When I set in the rear seat, my head was right against the edge of the rear glass mounting.
The 2007 XR model only available with a V6 engine(less economy).
