the fiat is totally different and for some strange reason there are loads where i live in milton keynes. wot a dilemma a v6 gtv or fiat coupe.
Overall I would say they are about equal.
The Alfa rides better, and handles a bit better but the Fiat is quite a bit faster, easier to tune (250bhp with just a chip and some colder plugs costing around £60 all in)
The V6 definitely sounds better though, but the 5 pot certainly still sounds pretty good and is smoother than the V6.
I could also get over 35mpg on a run with the Fiat plus it has 4 useable seats and boot.
As for styling, I much prefer the GTV but the Fiat does have some nice touches, that colour strip on the dash looks cool, it has a full set of gauges, oil pressure oil temp etc, and a nice fuel filler.
I also like the Ferrari style rear lights.
Have a drive in one, see what you reckon. It is very nearly an Alfa as they share so many parts and most on here will forgive you for owning one.
