2004 Infiniti QX56 4WD 4dr SUV (5.6L 8cyl 5A)
My wife purchased new after test driving escalade,denali,LX470 and Navigator. We did have brake problems at 15K but dealer replaced all rotors and pads and extended warranty from that time. This is an all around great SUV with every feature but most of all very comfortable and lots of space. Lots of power and for a 7600lb truck 16MPG is good, we now have 80K and were going to trade but it runs so good the wife wont let it go. I cant wait to see new model and we would trade for another.
