I haven't bought or driven a domestic car in over 20 years, but the test drive and apparent quality sold me on the Taurus. It is comfortable and fun to drive. It has great acceleration and makes virtually no road noise. I have not been disappointed since my purchase.
Ventilated seats (especially here in Florida), Sync system, back up camera, and blind spot indicator. The active motion seats are great, they provide a gentle massage that helps on long drives.
Perhaps better gas mileage, although I am averaging at least 22 mpg.
