Is this a real Shelby Mustang?

I don't think this car is actually a Shelby. Here's why I think that.

-I don't think white with silver stripes was available
-The badge on the steering wheel looks stuck-on (doesn't even look like the Cobra snake)
-The Cobra logos on the front headrests are uneven
-The wheels don't look like Shelby wheels
-The engine is a 4.6L V8 (the Shelby had a 5.4L V8)
-The autograph on the dashboard doesn't look authentic

Here's the car: http://www.ebay.com/...1072829591

Added (1). Is this a real or fake Shelby Mustang?

Added (2). I also think the stripe on the sides said "SHELBY GT500" instead of "SHELBY GT."

Added (3). I also think the navigation system is from another Ford model. I don't think navigation was available for the Mustang until 2010.

Looks like a Shelby GT, they made them from 2006 to 2008 (I think). It's a separate model than the GT500. The Shelby GT has a normally aspirated 3 valve 4.6L, just with a CAI and a tune, it was rated for 320 HP.
