honestly, at this point its whatever you want. your mind will tell you what you want. if you think a w7 honestly will beat it out, get that then.. because if you dont. you'll have the si and always be wishing you had the w7 and visa versa.
also look at the new xxx, and the new BA oval sub.
but in the end, its all in the mind, sq is subjective. Its like the chevy versus ford debate... just choose what you'd rather people see, and you have. and thats what is better.
because in the end, the only thing that matters is that you can live with it. and that you feel better for buying it.
i could get a w7 right now, and a friend could get a idmax.
if he thinks the idmax sounds better, than it does. and he spent his money alot better.
**** what everyone else says, get what is best in your mind. besides, the stupid fucks in your area will just have their bullshit anyway, what they read off the internet. time to prove them worng
