 I purchased my vehicle in Jan 07 and have 3700 miles on it.  This car is a dream to drive.  I had driven a van or suburban for 25 years and wanted something different.  I test drove the Lincoln Navigator and Cadillac Escalade but didn't care for them.  The Lexus was just too small.  I went ahead and purchased the QX56 even after reading some very bad reviews because I talked to several owners of the QX56 and they loved theirs.  The main problems I read were with the brake system.  Mine brakes just fine.  I feel very safe in this solid vehicle.  I get approx 14 mpg in town and 17 to 18 on the hwy. West Houston Infiniti is great. I wouldn't recomend Clear Lake - not very friendly.
