Howdy Folks! :) - Question again about 2 vehicles

Sorry I'm not posting much but I've been a busy woman.

I was wondering what your thoughts were on a Mazda6 (V6) or Xterra05 (standard V6). 4 doors on both ...basic package (nothing added except for alloy wheels and I think that's standard for both of the cars we're looking at.

We're seriously considering these 2.

this and the Altima (V6/4-door/spoiler).



We test drove the M6 yesterday and were IN LOVE!!! It can make a complete (full) turn around with no room at all ...nothing like our other cars and it speeds up to 70 in like 6 point something seconds. I believe that's what we're told, but we tried it and... it was definitely true. We can make the sharpest turns and S's w/little movement of the steering wheel ...and we took it around dangerous corners super fast. Of course the sales person tested these corners out and told us to trust him. My fiance said he wanted to break because it "felt" like there was no way he'd make the turn but sure enough... went in and out of it smoothly (and fast!!!).

We will test drive the Xterra soon.

Here's our situation:

We have a possibly 80lb dog who takes up TONS of room, 2 other SMALL furkids, possible kiddo in the FUTURE, and tons of military equipment with the desire and past history of traveling a lot.

I hear they corrected the "rugged" ride the Xterra had and increased its power.

Safety features on the Mazda were impressive as was its ratings on some sites we looked at.

We have a trade in that's worth $5,900. Plus it's been loved dearly by me.

That's all the info I have (from the unknowledgeable girl).

Thanks for your thoughts and opinions.
