I too have recently bought a 2008 2.5T Titanium X and like you, I love it (despite it being a humble Mondeo).
Mine's silver but doesn't look as nice as yours as it doesn't have the sport trim so the rear bumper is slightly different hiding the exhausts and I don't have that fancy red trim either which makes me sad!
I've never really bettered 25mpg but then again, I've never really tried that hard as it's quite addictive putting your foot down and letting the turbo kick in! (Childish, I know).
As for the blanking plate in the grille, mine doesn't have one but I don't have Adaptive Cruise Control either. (At least I don't think I do!).
