Not considering the bluetec...at this point I think we have decided on the X1 or X3. The Q5 is great but wifey prefers the fun factor, especially in the x1.
She wants the xline, terra, matte wood, 28i. Of course, I prefer the 35i, m sport, etc. If the 35i had that great 8speed as well, I'd probably force the issue, but she prefers mpg over thrust and the 28i is pretty stout in it's own right. I just have an issue with the pricing knowing that for a couple grand more we can get way more power and a better exterior. Happy though with any model, they are all fun.
Also, Now that I've driven the q5 more, I'll qualify my statement above - no doubt about it, the x1 35i is noticeably faster.
