The Maxima was great. I was actually driving it all day yesterday as I was getting a timing belt done on my X. I miss the way she drives, though. In my truck I drive like a granny partly because it's a truck, partly because it's lifted and partly because I don't wanna fill up every other day. When driving the Maxima, it's just way too hard to let go of the throttle. You just wanna go.
That said, I wouldn't take it over the X. My truck gets me places I need to go, can haul all my stuff and gear for camping along with a few people with room to spare. Plus, I can't wheel the Maxima.

And yeah... I love my X to death.
