Hi Danny, Ni------ce Gt. Saw a lovely 3.2GT in Ipswich - these cars just don't age/date. Got a 1.9 54 Gt and it's been the cheapest Alfa to maintain for me. Got my 3.2 Q4 on the first of March and still getting to know it. First impressions though are positive. I've got a 3.0GTV and it seems really unfair to compare the Brera/159 V6 to the Busso. I've had two Busso's and they remain, for me the gold standard for V6 design. However, they are history, but any modern V6 had to aspire to this guys jewel and they would not be what they are today without Busso. That said, 1st impressions of the GM derived V6 are that it is unfairly compared. The Busso would not want to lug all that weight around either. But the variable valve timing on the Q4 is quite an eye opener. When progressively applying throttle, the revs rise steadily until the cams start to advance, the revs climb and as a consequence and the ECU adds more cam advance. Then, just fleetingly, you get the sense of a Ferrari Kick in the back. Not overly so, but just enough for one to want to repeat the exercise. Of course it's not a Ferrari, but is a little peppery, peppery enough to want to repeat the exercise. I think it's a good engine and what Alfa have done with it deserves a fair bit of credit. I'm not sure, but I think the bore/stroke is not dissimilar to the 3.2 Busso. Oh! that the Busso had variable valve timing. Either way, my GTV has only 30k on the clock and I love everything about it, especially the engine. However, I think I'm falling in love with the GM V6. Besides, It's only the block, everything else is Alfa, and that can't be bad.
None the less, Had I been able to find a good 3.2 GT myself, that's what I would have had - good luck with yours - Brian
