OK, I'm about to lose my lovely Alfa Romeo 2.2 company car because it's very petrol-hungry and environmentally unfriendly which is bad considering I work for a government organisation...

. But they are replacing it at least, with one of these few:
Mercedes C Class
Ford Mondeo
Lexus IS
Which one!? The Merc drives very well apparently and looks great, the Ford is a great feeling thing having ridden in one, and the Lexus looks superb. All would be diesels and overall, the Merc will be fastest...
I normally know straight away what I want to drive, but I can't decide at all this time
