WTF. You cant compare this car to the old SHO
For 43k you get AWD, paddle shift 6 speed, heated AND cooled leather, keyless start, navigation, backup camera, blind spot monitors, and a TWIN TURBO V6.
Find me another car you get all that for 43k
The G8 is a completely different car.
Edit: Here is a close competitor :http://www.bmwusa.com/Standard/Content/Vehicles/2009/5/535ixDriveSedan/default.aspx
STARTING at 53k
