Going back to the question
But the burning question is which one for spirited driving? The V6 'S', the 2.2 'S' or the 1.75 TBi?
In my opinion depends where you do your spirited driving and what level of spirited driving you do. My example for instance as I'm near the alps you need something with some grunt to get out of the hairpin bends. I also drive back to the UK infrequently and it really is a grand tourer not a racing car. Q4 V6 for me is the best option. If you were looking for spirited driving on track I'm not sure the answer would be the same. Then how spirited is your driving, if very spirited then maybe this is not the best choice. Overall what do you want it to do ?
My suggestion, forget what you read and try and get some test drives with cars with updated suspension, it makes a huge difference. Then enjoy......
