I have the 5.0l V8 & love it:)
2011 model.
Awesome car.
I mostly drive it......whenever I can :) but avoid heavy traffic if I can.
The stopping & starting is a real fuel drain.
On a long trip I'd get around 10.5 -12 l/100 but in general weekly driving I'm averaging around 13-14l/100.
I drive quite sedately usually but I don't muck around getting to the speed limit.
I don't have to worry about turboes or any of those other expensive diesel issues and with the centre muffler replaced with straight through jobby it sounds awesome.
The video attached is going from no centre to the straight through.
Enjoy
