running costs for a 159 Diesel... er in a word (or rather two) bl**dy expensive!
How does your company deal with private fuel? It's a question I wished that I had asked. Usually companies that I have worked for have let me fill up all fuel using a card and they charge me a standard rate for private fuel I have used. Financially this works out ok.
Now I fill up and claim back mileage used for work. Until last month I got 12p per mile, now I get 14.7p per mile, and I'm pretty sure that it's still costing me money.
My Ti gives 34 mpg on a good day. a 1.6 Giulietta will be a fair bit better, a BMW will give high 50s, and a Prius 60mpg+
The other issue is the % charge. The Alfa is 24% of value, Giulietta less, BMW less still down to Prius at 10%!!!!

I wanted a Giulietta, but due to internal politics, they wouldn't let me have one, so pushed and got a 159 Ti. Don't get me wrong, I love the car but hell it's costing me (a fair bit more than my boss' BMW)
Or as Nev said, see if they offer cash instead. Not all do
