As for the Taurus outselling the Genesis, I would like to see the actual numbers as I have yet to see a Taurus on the road.
There are about the same number of Tauri as Genesi in Medford (about a half-dozen of each). Not bad considering that the Genesis sedan has been on the market twice as long as the new Taurus has.
The bottom line is, the Genesis has won awards and the Taurus HAS NOT.
The 2010 Taurus won "international car of the year" at the Los Angeles Auto Show.
The Taurus looks cheap and will never sell because Ford has the Fusion positioned against the like of Camry, Altima, Sonata and the Accord. That leaves no segment for the Taurus to compete in other than say the Maxima.
Why is that a problem? The Fusion competes against the Camry and the Altima; the non-SHO Taurus competes against the Avalon and the Maxima (while the SHO goes head-hunting for bigger prey). I'm not seeing a problem here.
The Genesis and SHO are different cars, but for $50,000 a loaded G37 will eat the SHO for lunch in every category, especially reliability.
What sort of reliability data do you have on a 2010 Taurus SHO?
The SHO is also far, far larger than the G37. Particularly if you care about back-seat passengers. If you don't want extra space, a larger car always seems "overpriced" and "heavy" and "slow." But not everyone wants a G37-sized car. After all, that's why Infiniti also offers the M. They wouldn't sell the M if everyone was happy with a G37-sized car.
Even better, wait for the Sonata turbo which will handily take on the SHO for $10k less. That is going to be my next car.
The Sonata Turbo doesn't have AWD, and its rear seat and trunk are both going to be a lot smaller. The Sonata Turbo may be the better choice for you, but that doesn't make it better for everyone else too.
