Thanks everyone for the warm welcome!
Welcome to AO
Keep the 2.4, it is an Italian engine!
Thanks for the advise! That's what I'm going to do for the moment, and I agree the 2.4JTD is a terrific beast on its own. I love its punch and how you have to work your way through the gearbox keeping the revs a little high if you want to get the most out of it. Definitely one of the better diesel engines out there, and if I keep it, I'll probably be remapping it in a year or so when the guarantee expires.
But sometimes I miss the sound of a petrol engine and the smoothness of an atmosferic one. The 3.2 (while coming from Australia), seems to be a very "modern" option, with a flexible response. Additionally, I wouldn't mind having AWD, and by the way, I would have fitted my 2.4 with Q4 hands down if there was such an option. I don't understand why they offer it for the 159 but not for the Brera.
