To add to the comment above about going out for a drive. A must for whatever you do.
Now I, as a rule hate diesels and do moan about the clatter etc, however you should try them first. I have heard on more than one occasion (Alfa dealer too) that the JTD was the best all rounder for the GT. Loses that 'Alfaness' a little because sports cars should have spark plugs but nevertheless it is a hoot to drive that clatterbox, loose spanners dieseasal
I personally don't think the mileage matters, the drive does. There are folk that would buy a diesel over a petrol all day and not just for economy.
Agree with a lot of that.
I've had a lot of diesels in my time, mainly because I've been cash-strapped for a lot of my time on this planet, haha!
However, the torque this GT puts out does make it pretty fun to drive and certainly surprises a lot of larger-engined petrol cars (albeit for a few seconds till I change gear...)
The noise from inside the cabin I don't mind - in fact, I'd say it has a bit of a rorty-note to it on the move, though obviously not as much as the 5pot. What I don't like, however, is the clatter from outside the car.
The GT looks like a luxurious coupe. I thought people on this site were just being silly when they talked about getting looks, but no; since I've bought it, I've noticed people looking at it as I go by or when I sit in traffic.
But the clatter of the diesel engine up front doesn't suit the striking looks of the car.
I've invested a lot of money into my particular car getting it spot on - it needed work doing to the engine etc to get it perfect, as well as a new clutch and remap etc. I'm happy with it for now.
But - BUT - if it does decide to throw more problems my way in future, I'd be very tempted to trade it in for either a 156 or a GTV (either in V6 form). Purely for the noise and general 'Alfaness.'
