Agree with you ukmike2008 that many of these surveys may not be statistically robust, I mentioned this point in my post when I said that "these surveys can be unrepresentative"
However, I would contend that if Alfa were building poor cars they would not finish 4th overall, the Mito would not have finished 1st in the Supermini category and the 159 would not finished 4th in the Compact Executive category. Would the 33, 145/6 or 75, all Alfas I like, achieved such results? I doubt it despite their strong merits and charms.
I must say the 159 result resonated with me as I think its a seriously underated car. I've owned a 159 2.2 JTS for three and a half years and, touchwood, it has been a joy to own, great to drive and with its stunning looks theres a huge incentive to give it a regular wash-n-polish. I still contend that the 159 deserves greater sales success, Alfa's poor marketing of the car is a big part of the problem, not having the 159 at the Bologna Show is typical and poor decision on Alfa Romeo's part imo.
