2004 BMW 6 Series Coupe 645Ci 2dr Coupe (4.4L 8cyl 6M)
The feel good factor is priced in!
 The 645 is truly "sport" luxury.  Not nimble and quick but muscular and responsive.  The extra horses of the 650 should help.  The iDrive is not difficult...if you can't figure it out you most likely can't afford the car anyway!
