-5.0i comes with a sexy titanium grill and wide exhaust.
-Even with turbo lag, I'm assuming it pulls more on average during the lag period than the 3.5i?
-It does consume plenty of fuel but I managed almost 20mpg on my one way trip from Norcal to Socal (in one tank) with the car full of boxes and people.
-They are way less common
-The Performance package gives you 50 more torque with no change in mpg
-The growl during acceleration is insane
