Hi. Yes, sorry to mention it's a 2.0L diesel twin turbo.
I think from reading reviews that the differences are with engines, suspension (stiffer) and steering. Also DRL's are permanently on for European roads.
The options I have on my Titanium are Automatic transmission, sport wheels, panoramic roof (or moon roof as you say) Lux pack, (heated and cooled leather seats), Sony sound system and adaptive headlights. (I think that's them all).
Lovely car, turns heads over here as there aren't that many about.
I love those rear lights!!
