Sorry Drellis just catching up.
The Alfa GT JTD, in a word, buy it!
I have had a 1999 GTV 2.0TS, 2001 156 1.8TS, 2004 GTV 3.2V6 and a 2007 GT 1.9JTD
Now, the worst engine was the 1.8 just because it was a bit gutless, the 2L TS was very very good, but the top of the pile is the 3.2V6 simply a stunning engine. Now the JTD is a different kettle of fish. Its powerful like the 3.2 but economical too. I know the figure 0-60 are some 2 seconds apart, but the JTD pulls like a train and returns 500 miles per tank, the 3.2 about half that, so the question is, is the 3.2 worth twice the fuel to you, if it is, then buy it, but if you are unsure, then buy the JTD you will not be disappointed, plus you can chip it to either 170bhp or 200bhp for something ridiculous like £250
I have a 150bhp Lusso with Bose hifi and as a cruiser, life does not get much better. Ok if it was my main car, then I would go petrol, but this is just a runabout to load the miles onto, I will always have my toys.
