i would go with diesel, they sound just as good, get better mileage (obviously) and still deliver as much power or even more.Waiting for a test drive first!
I've driven Alfa Romeos for 20 years, so I won't order until I've driven the Ghibli. The Alfa replacement for the 159 isn't coming out until at least the end of 2014, so I want to go for the Ghibli.
Also, undecided between diesel and petrol.
Should get our first demonstrator models in the UK in the next couple of weeks.
Would like to place an order soon after. Probably about 3 month delivery for a factory order, but my dealer expects to have at least 18 coming through the system by Christmas. I'm fussy about options, so will probably have to wait until March next year for mine. In the UK that will be the "14" number plate which comes in on 1 March.
