回複：回複：Q7, or MB GL

GX doesn't handle as well as the other 3 on highways. It's also the only model of the 4 that isn't considered a luxury SUV by Robb Report.

X5's 3rd row is a joke, it's not a real 7-seater. Q7's is marginally roomier. GL has the best packaging.

Q7 is marginally sportier than GL. I test drove them both and decided that GL's extra practicality is a bigger plus. Had it for 2 years now and still love it.
